A "dangerous" mental health patient who disappeared from a psychiatric clinic is being sought by police.
Reece Burton, 25, was being held at the North London Clinic in Enfield after being convicted of grievous bodily harm with intent and detained under the Mental Health Act.
He was last seen at the unit at 11.20am on Friday, Scotland Yard said, where he was on permitted ground leave.
Police said he was considered dangerous and should not be approached by the public.
A Met spokesman added: "Burton was last seen wearing a blue T-shirt, blue jeans, a black baseball cap, a grey parka jacket and a pair of grey trainers.
"He has a distinctive tattoo on the right side of his neck with the initials 'RB'.
"He was known to previously frequent Havering, Waltham Cross and Haringey."
