Six men and one woman died in the Croydon tram crash
Six men and one woman died in the tram crash in Croydon, south London, British Transport Police (BTP) said.
A force spokesman said officers were working with the coroner to identify the victims.
The tram driver, a 42-year-old man, from Beckenham, was released on bail after being arrested on suspicion of manslaughter.
Investigators said the tram was travelling at a "significantly higher speed than is permitted" and are probing whether the driver had fallen asleep.
