CCTV has been released of a man who has been missing since attending a party a month ago.
Andrew Cooke has not been seen since leaving a squat party in a disused car showroom in Lea Valley Road, Chingford.
The footage shows the 29-year-old visiting the Shell petrol station on the corner of Lea Valley Road and Sewardstone Road soon after leaving the party at 4.30pm on February 12.
His father, Graham Cooke, 58, said: “It’s the first break we’ve had so that's good news.
“There must be people who saw him at that time but we have no lead from there so it’s a complete mystery.”
Mr Cooke, from Crystal Palace, was pictured wearing a maroon hoodie under a dark zip-up jacket, with dark jeans or trousers and black shoes.
He has dark ginger hair, a pierced nose and had red paint on his face at the time of his disappearance. Police have asked residents to check gardens, outbuildings and sheds.
Anyone with information is asked to call police on 02072326246, or 999 if urgent.
