Members of the public have been warned not to approach a mentally ill man who has gone missing from a medium secure mental health unit.
James Frank Lisbon has not been seen since August 4 when he was allowed out of the John Howard Centre, Kenworthy Road, Homerton, for a period of unescorted leave.
The 34-year-old man is described as 6ft and of large build.
When he was last seen he was wearing a navy blue short-sleeved top, navy tracksuit bottoms and a white baseball cap.
He has scars on both arms and a tattoo on his right arm.
Mr Lisbon is believed to be in the east London area.
A Met police spokesman said: “Members of the public are warned not to approach him. We are concerned for his well being as he requires treatment.”
Anyone with any information as to his whereabouts is asked to call 999.
