Police are renewing their appeal to trace a man who has been missing for three weeks.
Mohammed Mboob left a hospital in Enfield midway through treatment on June 28.
He requires regular medication that he does not have with him.
The Metropolitan Police said Mohammed should not be approached by members of the public, particularly women, and that anyone who does see him should call 999.
Mohammed is believed to attend local music studios to record music.
Police have been working around the clock to locate Mohammed, including door to door and CCTV enquiries, and have issued appeals via social media.
He has links to Brent Cross, Bromley and Hackney.
Anyone who has information as to his whereabouts should call 101 or tweet @MetCC ref 23MIS021563, Scotland Yard said.
Immediate sightings should be called in via 999, they added.
