The security services were facing difficult questions last night over how at least one of the London Bridge terrorists slipped through the intelligence net.

It emerged that the 27-year-old Muslim extremist appeared in a TV documentary last year about British jihadis – and was involved in a filmed altercation with police after an Islamic State flag was unfurled in a park.

He was caught on camera alongside two notorious preachers who were well known to police and intelligence officials because of their extremist views.

Amid a series of revelations last night, it was claimed that a friend of the Watford-born suspect had reported him to the anti-terror hotline after he became radicalised by watching extremist videos on YouTube.

It was also alleged that police were warned about the suspect radicalising children in a local park two years ago.

And yesterday, a photographer captured a detective carrying secret notes which appeared to suggest a man embroiled in the investigation had been quizzed by police last year.

The suspect, who the Mail has chosen not to name at the request of police, is understood to be one of three men who embarked on a stabbing rampage in London on Saturday night.

The attackers, who were wearing fake suicide bomb vests, used a van to mow down pedestrians on London Bridge before running amok with knives in Borough Market, slitting the throats of innocent bystanders. One is reported to have yelled: ‘This is for Allah.’

They left at least seven dead and 48 injured before police marksmen halted their stabbing spree.

Last night, chilling footage showed two of the attackers sauntering through a deserted Borough Market just moments after they abandoned the white van they used in the attack.

Yesterday, Theresa May declared that ‘enough was enough’ as she announced a four-point plan of action following the third devastating terror attack in Britain in just three months.

But the Prime Minister insisted that Thursday’s general election would go ahead, despite terrorists trying to derail Britain’s democracy. On another day of extraordinary developments:

  • Police revealed they had fired an ‘unprecedented’ 50 bullets to kill the three London Bridge terrorists because they believed the attackers were wearing suicide belts;
  •  A member of the public was accidentally shot by police officers in the crossfire but is expected to make a full recovery;
  • As details of the first victims emerged, the authorities said 36 people remained in hospital, with 21 in a critical condition;
  • The Prime Minister said there had been ‘far too much tolerance’ of the ‘evil ideology’ of Islamist extremism;
  • She also declared war on the internet giants for providing a ‘safe space’ for Islamist terrorists bent on attacking Britain;
  • However, it soon emerged that terrorist propaganda and guides to carrying out terror attacks were still freely available online;
  • Labour leader Jeremy Corbyn tried to make political capital out of the tragedy, accusing the Mrs May of denying resources to the police and security services;
  • But he U-turned on his previous opposition to the police shoot-to-kill policy and backed the PM’s insistence that the general election must go ahead on Thursday;
  • Amid enormous security, the One Love benefit concert got underway last night after a one-minute silence for the 22 victims who lost their lives in the bombing at the Ariana Grande concert at Manchester Arena two weeks
