British Transport Police officers are continuing to work at the scene of a major incident in Croydon.
Emergency services were called to a tram derailment near Sandilands tram stop at 6.13am on Wednesday 9 November.
At least seven people are now confirmed as having died as a result of the incident.
Deputy Chief Constable Adrian Hanstock said: “This is a tragic incident and our hearts and thoughts go out to all those affected.
“When officers arrived on scene shortly after 6am, they were met with a complex and challenging situation.
“Together with our partners from the other emergency services and with support from London resilience agencies, they have worked through the day and night, at the scene.
“After liaison with the Coroner, we can confirm that at least seven people have lost their lives as a result of this incident.
“Our officers continue to work tirelessly to formally identify them and provide care and support for their families.
“Identifying those who have died can be a complex and lengthy process and we want to ensure we get this right.
“We expect to be at the scene for at least the next 12 hours, continuing searches and carrying out forensic examinations in support of the investigation into the circumstances, and in order to provide a report for the Coroner.
“Today (Thursday 10 November), we are assessing how and when it is appropriate to recover the tram and remove it from the tracks.
“I want to thank everyone who assisted at the scene, and behind the scenes, in Croydon.
“In the coming days, we will continue to work alongside the Rail Accident Investigation Branch to establish the circumstances of how this happened.
“At this stage it is too early to speculate on a single factor being the cause of this incident.”
A 42-year-old man arrested in connection with the incident has been released on police bail.
