Trump Was Right! Brits Had Arrested Suspected London Underground Bomber Two Weeks Earlier.

Just hours after a homemade bomb ripped through a London Underground car, injuring 30, President Trump tweeted that British police had had the attacker “in their sights” and should have been “more proactive” in catching “the loser.”

Scotland Yard hit back, saying Trump’s comments were “pure speculation” — but refusing to name the suspect. Others said Trump’s tweet was “idiotic” and “extremely unhelpful.”

Prime Minister Theresa May said: “I never think it’s helpful for anyone to speculate on what is an ongoing investigation. The police and security services are working to discover the full circumstances of this cowardly attack and to identify those responsible.”

But now it turns out that Trump was, in fact, right, The Daily Mail reports.

The 18-year-old being held by police on suspicion of planting a bomb on the London underground was arrested two weeks ago at the exact same tube station where the device exploded but released, neighbours have said.

The teen – who is being held after police tracked him to the departures hall at the Port of Dover – is thought to have been a ‘problematic foster child’ who was raised in Sunbury-on-Thames by Penelope Jones, 71, and husband Ronald, 88.

Serena Barber, 47, who has known the couple all her life and lives in a property backing on to theirs, said: ‘They have two boys at the moment, both are foreign. One is very quiet and polite, the other who is 18 is awful.

‘I know about two weeks ago he was arrested by police at Parsons Green, for what I don’t know and returned back to Penny and Ron. After that Penny said she was going to have to stop caring for him, she couldn’t handle him.’

The revelation comes after President Donald Trump tweeted that the ‘loser terrorist’ behind the latest London attack was ‘in the sights of Scotland Yard’ – and heaps pressure on the force to reveal whether he was detained and why he was released.

A neighbor of the house raided, Stephen Griffiths, 28, told the Mail that police had been at the house numerous times in recent weeks.

He also saw officers using drones to search the garden at the back of the property. He said: ‘Police have been at this address a few times in the last couple of weeks. At the time we just put it down to it being foster kids that needed to be spoken to.

‘But it clicked in my head earlier – what if one of the children was under investigation or surveillance? Why couldn’t something be done sooner to stop this happening? Why couldn’t the police have questioned him? Three or four officers would turn up and would speak to the foster parents on the doorstep.

‘They were in normal police cars but they weren’t wearing police hats or reflective jackets – they were dressed all in black. It was nothing like just a normal officer doing a duty call, it seemed like something a bit higher in the chain. The other day they were out there for a long time – a few hours – and they could have even gone in the house.’
