A man with paranoid schizophrenia who stabbed a stranger at a Tube station has absconded from a mental health hospital for the second time.

Mark Ricketts, 47, escaped from Springfield Hospital, Tooting, south London, on Saturday evening.

A Met Police spokesman said he does not have his medication and "extensive efforts are underway" to find him.

Ricketts stabbed Mark Kemp in the stomach with a large kitchen knife at Tooting Broadway Station in 1993.

He first escaped from Springfield Hospital in 2004 while he was on a day visit from Broadmoor Hospital where he was being treated for mental health problems.

An investigation found he absconded after staff took him on an unplanned walk outside a secure area.

Police are advising the public not to approach Ricketts and to call 999 immediately if they see him.

He is described as black, 6ft 2ins and of large build. At the time he went missing he was wearing a blue tracksuit top and bottoms and black trainers.
