David Clark, who was an Australian national, was killed in Borough High Street at around 12.30am on January 7.
An investigation has been launched into the incident by the Independent Office for Police Conduct (IOPC).
It found that two Met Police vehicles were travelling south on Borough High Street responding to an emergency call.
Sirens were activated and both police vehicles had their emergency lights on, according to the independent watchdog.
As the driver of the first police vehicle passed through the junction at Great Suffolk Street and Trinity Street, they were involved in a crash on the road with Mr Clark, who appeared to be crossing the road.
The drivers of both police vehicles stopped at the scene and first aid was immediately provided to Mr Clark.
Mr Clark, who lived in Scunthorpe, Lincolnshire, died at the scene.
OPC Director Amanda Rowe said: “Our deepest sympathies are with Mr Clark’s family and friends both in the UK and in Australia, and everyone affected by his death.
“We have met with his family to advise them of our investigation and they will be provided with regular updates. They have requested privacy at this difficult time.
“Given a member of the public has died in an incident involving police, it’s important that an independent investigation is carried out to establish the full circumstances.
“Our investigation is in its early stages and the officers involved are currently being treated as witnesses.”
Further CCTV and police body worn video footage is due to be reviewed later this week.
