Police are warning people not to approach a missing tattooed man who may be in need of urgent medical treatment.
John Thompson was at Croydon University Hospital last night for a mental health assessment but left at about 11pm before he was seen by medical staff.
The 31-year-old, of no fixed address, has a swallow tattoo on his neck and a tear tattoo on his face, and is slim with ginger curly hair.
He regularly visits High Holborn and Camden and has family from Durham.
Anyone who sees him is asked to call 999 immediately.
If you have information on his whereabouts then you are asked to call the police non-emergency line on 101 or the missing persons unit on 020 3276 2139.
