Detectives have released images of four witnesses they are keen to trace, after a man was stabbed on board a London train in front of horrified passengers.

Rakeem Thomas, 19, has been charged with attempted murder and possession of an offensive weapon following the incident, which happened near Beckenham Junction at roughly 4pm on March 27.

A man in his 20s was taken to hospital where he was later said to be in a “critical but stable condition”.
