Five drivers who may have been involved in a suspected multiple hit-and-run in which a woman died have been traced, police said.
The 29-year-old pedestrian, who was Polish but had been staying in Wandsworth, south London, was hit by a lorry as she used a pedestrian crossing while the traffic lights were green.
It is thought she was then struck by another lorry and up to three cars, and officers said none of the drivers stopped at the scene in Tulse Hill, also south London, on Monday morning.
A 49-year-old man who was driving the first lorry was interviewed under caution earlier this week while a 52-year-old driver of the second car was released under investigation following his arrest on Tuesday evening on suspicion of causing death by careless driving.
The driver of the first car and second lorry have now also been traced and spoken to, as has the driver of a third car which police believe may also have struck the woman.
None of these three people – for whom the police did not give ages or genders – have been arrested.
CCTV released earlier by police showed a white lorry and a black car which are thought to be the second and third vehicles involved in the collision.
Scotland Yard said further analysis of footage established that a third car may also have hit the woman, whose family arrived in London on Friday to formally identify her.
A post-mortem examination revealed her provisional cause of death was multiple injuries.
Despite tracing the five drivers, officers are continuing to appeal for information from witnesses, the Press Association reported.
Acting Detective Sergeant Alastair Middleton said: “Even though we have traced all the vehicles that we believe were involved, I continue to appeal for anyone who witnessed the collision and the moments afterwards to contact us immediately.
“We want to hear from anyone who travelled from the South Circular junctions of Norwood Road going towards the junction of Brixton Hill between the hours of 6.30am and 7am on the day of the collision.
“We are particularly interested in any dashcam footage that may have captured some of the incident before or after the collision.”
