Investigators believe three victims were killed on the bridge, including one man who was thrown into the River Thames, before the attackers left the vehicle and stabbed five people to death around London's busy Borough Market, Haydon said.
An undated handout photo issued by the Metropolitan Police, London, and made available on Sunday June 11, 2017 of a fake suicide belt worn by one of the London Bridge attackers in the attacks of Saturday June 3 which killed several people and wounded dozens more.
Dean Haydon, the Metropolitan police commander, who is leading the counter-terrorism investigation, said the fake suicide belts made the courage of police and members of the public who confronted the terrorists even more remarkable. "It could be that they had plans to take the attack into a siege situation or it might be that they saw it as protection from being shot themselves", he said in the statement.
In an account of the June 3 attack released by the Metropolitan Police, Cole said he arrived at Borough Market to find "casualties on the pavements".
Early on Saturday, police said they had arrested a man, 27, on suspicion of preparing terrorist acts, after carrying out a raid in Ilford, east London, linked to the London attack.
The images of the three belts have been released to the public this morning.
Police found petrol bombs and blowtorches in the van, which crashed on the bridge.

Eighteen people have been arrested in connection with last week s attack.
He rented a different van later that evening. In total, eight people were killed and 48 others were injured in the attack.
Police raided Redouane's small residence on Tuesday and said he had been renting it since April.
The van was packed with sacks of gravel and chairs, possibly to increase its weight as a "battering ram".
"I managed to grab a couple of armed officers and they escorted my medic, and another police medic, up to London Bridge".
Police said they found a copy of the Quran opened at a page "describing martyrdom" at one of the attackers' houses.
After Butt's payment was declined, the trio of terrorists rented the smaller van that they used to plow into crowds before jumping out of the vehicle and going on a stabbing rampage that left eight people dead and nearly 50 injured.
Inspector Cole recalled trying to reassure the people in the basement as the drama unfolded on the streets above.
"But we also have some quite volatile individuals who go from having what you and I would regard as utterly vile extremist views to being motivated to carry out an attack".
