Armed police swooped on East Ham at 3pm to raid a flat in connection with last night's terror attack on London Bridge.

But pictures emerged of the scene turning into a stand-off with officers pointing guns towards a flat above a betting shop.

The officers could be heard in footage shouting "show us your hands" and "he's on the balcony" as the man leaped from roof to roof.

Reports suggested the man was holding a gun as he tried to make his getaway.

Shimmy Ali, 32, who was out meeting a friend for lunch, said: 'I was at the crossing near Paddy Power and heard a woman with a baby start screaming.

"I looked and five masked men with guns were smashing into the flat.

'It took me a minute to realise they were police. A few seconds after they went in a black man wearing a grey vest and blue joggers climbed out of the window above Paddy Power.

"A police marksman on the other side of the road was screaming to go back inside and saying he would shoot him.

"The man jumped onto the roof of Sam's takeaway and then across to Barking Food and Wine - that's where another officer managed to reach out and grab hold of him.

"He got dragged back inside and then about 20 more armed officers arrived. Within about 20 minutes there were many more uniformed officers on the scene.

'They moved us way back so I could not see what happened to the man, I can only assume he was arrested.

"It was absolutely terrifying, I'm still in shock to be honest."

Some locals since said three men were later seen being taken away in ambulances, although there are also conflicting reports the three men were arrested.

The Metropolitan Police have only since confirmed the raid was carried out in connection with last night's attack.

The atrocitiy on London Bridge has so far left seven dead and 48 injured, many of whom are critical.

The three suspects in yesterday's attack were shot dead by cops after they ploughed into pedestrians on the bridge in a white B&Q van.

The attackers had jumped out of the vehicle and attacked multiple bars and restaurants, stabbing people and brandishing 12in-long hunting knives.

Police announced in a press conference this afternoon, in which they confirmed the East Ham raid, that 50 rounds of bullets were used by cops last night.

Early this morning cops carried out a raid in Barking and arrested 12 people.
