Dramatic footage of the moment armed police shot last weekend’s London attackers dead has been leaked on a pro-police Twitter account.
The video shows chaotic scenes as men attack people on the street before a police car arrives and armed officers shoot several attackers.
At one point an officer appears to collide with an attacker, the two of them falling together. The officer later stands, the attacker's body remains motionless.
Police have confirmed the attackers were wearing fake suicide vests.
"I'm not sorry for sharing it - people need to see it," the Twitter user wrote.
UK Police haven't confirmed the authenticity of the footage, but said they were "aware" of images circulating on social media.
The apparent CCTV footage - played a Dell computer screen and recorded on a handheld device - matches details of Stoney Street, Borough Market, the location where police confronted the attackers.
British Police have been praised for responding quickly to the attack, killing all three perpetrators within eight minutes of initial emergency calls.
The Independent Police Complaints Commission, which investigates all police shootings, has said they are examining CCTV footage from within Borough Market.
“We can confirm that 46 shots in total were fired by eight police officers – three officers from City of London police and five from the Metropolitan police service," they said in a statement.
The Twitter account which released the image has 600 followers and tweets consistently on the importance of arming UK police officers - it has posted videos of several previous attacks.
Eight people were killed and dozens injured when a van rammed into pedestrians on London Bridge and attackers then went on a stabbing rampage at nearby Borough market.

Two Australians have been named among the dead, which also included three French citizens, a Canadian, a Spaniard and a British man.
Police received reports of a van speeding into pedestrians on London Bridge at 10:08pm (2108 GMT).
After deliberately swerving into people, the van crashed on the wrong side of the road into fencing and a traffic light by Southwark Cathedral, on the south side of the bridge.
Eyewitnesses said they shouted: "This is for Allah".
London's Metropolitan Police have identified the attackers as Khuram Shazad Butt, Rachid Redouane and Youssef Zaghba.
Butt, 27, was a British citizen born in Pakistan known to security services and even featured in a television documentary entitled "The Jihadis Next Door".
He was investigated in 2015 but he was "prioritised in the lower echelons of our investigative work" and there was no evidence of "attack planning", police said.
Redouane was 30 and "claimed to be Moroccan and Libyan", national counter-terrorism police chief Mark Rowley said in a statement. Ireland's national broadcaster RTE reported that Redouane had an Irish residency card and had lived in Dublin.
Butt and Redouane both lived in Barking in suburban east London.
Police said Zaghba was an Italian national of Moroccan descent, living in east London.
Police said neither he nor Redouane was known to police or security services.
The Islamic State jihadist group claimed responsibility for Saturday's attack.
