CCTV images have been released of a terror suspect being hunted by police.
Mohammed Ahmed Mohamed was last seen at a west London mosque on Friday afternoon.
He entered the building wearing Western-style clothes, but CCTV images issued by Scotland Yard later show him leaving with his face and body fully covered by the traditional Islamic garment.
Mohamed is "not considered at this time to represent a direct threat to the public", Scotland Yard said, but urged anyone who sees him to call 999 immediately.
