The British Transport Police has re-questioned the driver from the Croydon tram crash.
Seven passengers died and more than 50 were left injured when a two-carriage tram derailed and overturned at Sandilands junction on the London Tramlink system. The incident happened at around 6.10am on November 9.
The 43-year-old tram driver was previously arrested on suspicion of manslaughter and released on bail.
After being returned to police custody for further questioning, he was once again released under police investigation with enquiries continuing.
In a statement released on September 20, senior investigating officer Detective Superintendent Gary Richardson said, ‘This is a complex enquiry and we have a team of detectives who are dedicated to investigating the cause of the derailment.
‘There has been good progress in the investigation since the incident last November and today we further interviewed the driver.
‘We have released him under investigation as we now finalise the report for the Crown Prosecution Service.’
