Theresa brands Trump 'unhelpful' after he Tweets that 'loser' Tube bomber was already 'in the sights of Scotland Yard' as he uses blast to push his security agenda
- Donald Trump said Friday morning: 'Another attack in London by a loser terrorist'
- Trump tweeted suspects had been 'in the sights of Scotland Yard' ahead of time
- May ally Nick Timothy said Trump 'doesn't know' anything and was 'unhelpful'
- A crude device set off Friday on London's Tube could have killed dozens
- The bombing injured at least 22 people, including a ten-year-old boy
Theresa May today slammed Donald Trump for speculating publicly about the police investigation into Parsons Green bombing.
The Prime Minister's intervention came after the Met criticised the tweets about the Parsons Green bomb as 'unhelpful' and 'pure speculation'.
The President claimed in a Twitter rant that officers had the suspect 'in the sights' despite Scotland Yard refusing to confirm the details of any man hunt.
Speaking from Downing Street after chairing a meeting of the Government's emergency 'Cobra' committee, Mrs May said: 'I never think it's helpful for anybody to speculate on what is an ongoing investigation.'
Speaking to journalists in Washington this afternoon, Mr Trump said he planed to call Mrs May 'right now' to speak about the attack.
Mr Trump's Tweets came at almost exactly the same time as Met Assistant Commissioner Mark Rowley gave an initial update on the attack in a TV statement.
Standard police procedure in the aftermath of any terror attack is to keep the identity of any suspects confidential.
A backlash against Mr Trump's Tweets was growing today as former No 10 chief of staff Nick Timothy slammed the messages and senior MPs warned it could undermine the police investigation.
Theresa May publicly rebuked the US administration after the Manchester bombing when shared intelligence was released to American media.

President Donald Trump has claimed Scotland Yard knew ahead of time about a bomber or bombers who set off a crude incendiary bomb Friday morning on London's 'Tube' subway

Trump tweeted: 'Another attack in London by a loser terrorist.These are sick and demented people who were in the sights of Scotland Yard. Must be proactive!'

Mr Trump's used today's tirade to promote his plans for a travel crackdown on Muslims wanting to visit the United States.
A Met Police spokesman said: 'The comments are unhelpful and pure speculation.
'If anyone has got any evidence or information, please contact the anti-terrorism hotline.'
The force declined to give when asked by MailOnline if they had a suspect, evidence of a wider plot or of any suspect was seen on TV.
Labour MP Stephen Doughty, a member of the Home Affairs Select Committee, told the MailOnline: 'Comments like this from President Trump, or anyone else, are extremely unhelpful.
'The full focus must be on allowing the police and security services to do their job, and those responding at the scene to the emergency and tending to those injured.
'Continual speculation and breaching of intelligence and security sharing by the US President has the potential to not only undermine a vital relationship, but also to prejudice investigations into this and other incidents.'
Mr Doughty said it is 'obviously not the first time' key pieces of information about a terror attack have been leaked by the US, after details of the Manchester bombing investigation were printed in American newspapers.
He said: 'This is obviously not the first time we have seen these unhelpful comments and I hope that the British government will be responding in the strongest terms to remind President Trump of his responsibility in these situations.'
Mr Timothy tweeted: 'True or not – and I'm sure he doesn't know – this is so unhelpful from leader of our ally and intelligence partner.'
London Mayor Sadiq Khan - who has clashed publicly with Mr Trump before over London terrorism - told LBC today he had not seen the tweets but insisted the focus must be on allowing the police to get on with their job.
He said: 'What is important is cool, calm heads are heard now.'

Theresa May's former adviser Nick Timothy reacted to Trump's intervention by saying the president 'doesn't know' anything: 'This is so unhelpful from leader of our ally and intelligence partner'

Trump added: 'Loser terrorists must be dealt with in a much tougher manner. The internet is their main recruitment tool which we must cut off & use better!'

In his twitter rant the President said: 'Another attack in London by a loser terrorist,'
'These are sick and demented people who were in the sights of Scotland Yard. Must be proactive!'
A former adviser to British Prime Minister Theresa May chimed in almost immediately on Twitter to insist Trump doesn't know what he's talking about when he suggested police missed the chance to stop the bomber.
'True or not – and I'm sure he doesn't know – this is so unhelpful from leader of our ally and intelligence partner,' wrote Nick Timothy.
The source of President Trump's allegations against the British police are not yet clear. However, this development could reignite the diplomatic row between the UK and the US over the leaking of sensitive police information.
Trump wasn't done, adding in a second tweet: 'Loser terrorists must be dealt with in a much tougher manner. The internet is their main recruitment tool which we must cut off & use better!'
The president also linked Friday's attack at the Parsons Green station attack to his controversial travel ban.
He said: 'The travel ban into the United States should be far larger, tougher and more specific – but stupidly, that would not be politically correct!'
Completing his tweetstorm, Trump drew attention to his administration's military action against ISIS and said should the US should get more aggressive with terror groups.
'We have made more progress in the last nine months against ISIS than the Obama Administration has made in 8 years. Must be proactive & nasty!' he wrote.

Police in and around London are hunting for the 'bucket bomber' who tried blow up a rush hour Tube train amid claims that he is armed and may have left other devices

The crude device could have killed dozens but failed to properly detonate and sent a 'wall of fire' through a subway car, injuring at least 22 people including a ten-year-old boy
The latest version of Trump's travel ban, initially announced in a botched late-January rollout, calls for a ban on people entering the U.S. from six terror-prone countries that are also Muslim-majority nations.
It also bars the entry of most refugees from anywhere in the world.
Federal court challenges have resulted in exceptions being made for travelers who already have established ties to the U.S., including a broad definition of what counts as a close family member.
The U.S. Supreme Court is expected to hear oral arguments to decide the ban's constitutionality in October, but allowed it to go into effect last month while the case is pending.
Police in and around London hunted Friday for a 'bucket bomber' who tried to blow up a rush hour Tube train amid claims that he is armed and may have left other devices.
The crude device could have killed dozens but failed to properly detonate and sent what was described as a wall of fire through a subway car, injuring at least 22 people including a ten-year-old boy.

Terrified passengers reportedly ran for their lives and were seen covered in blood with scorched hands, legs, faces and hair after the incident in west London during the morning commuting rush hour.
Photographs from the District Line train show what experts believe is a 'pretty unsophisticated' bomb in a flaming white bucket inside an insulated freezer bag bearing the logo of the 'Lidl' European grocery chain.
Christmas tree lights are also shown connected to a battery protruding out of the top.
Witnesses said there was a loud 'bang' and a flash – and then a ball of flame engulfed surrounding passengers.
Scotland Yard said it was a terror attack but would not officially confirm claims that there is another device or that a suspect is on the run.
But an officer at the scene told MailOnline: 'We believe there is a second bomb – there is a man with knives on the loose.'
Luke Warsmey said the explosion was like a 'giant match' sparking and he saw a woman with no skin on her legs and a ten-year-old boy with a burned body.
He said: 'People just started sprinting. It was sort of every man for himself when that happened. The burn victims had severe leg injuries.
'It was a very busy commuter train, young and old, school children going to their schools. I saw was nannies trying to look for kids, because of the rush of people just taking five- and six-year-olds away from them and they were trying to look for them.'
