The man driving the Croydon tram which crashed and killed seven people has been further questioned by police on suspicion of manslaughter.

Alfred Dorris, 43, from Beckenham, was arrested at the scene of the incident in November 2016.

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."

The crash left seven people dead and 51 injured.

Around 70 passengers were on the two-carriage tram when it came off the tracks, overturned and slid for 25 metres.

An interim accident report found it was travelling at 46mph as it entered a sharp bend at Sandilands Junction, which had a 13mph limit.
