The family of a man who went missing after attending a rave in a disused car showroom almost three weeks ago have asked other clubbers to help find him.

The family of Andrew Cooke, 29, are becoming increasingly concerned as they face an agonising wait for news.

The Crystal Palace resident has not been seen since leaving the party in Chingford between 3pm and 4pm on February 12.

His family have visited the area to try to establish how he left and where he went after.

His uncle, Brian Cooke, 63, said: “We gave out more than 2,000 leaflets and probably spoke to two or three times that number altogether.

“We have three alleged sightings of him during last weekend, all of which are being followed up by police.

“If we can work out which direction he went in, after leaving the venue, it might help us and therefore help the police.”

Mr Cooke, known as Cookie to his friends, is white, very slim and about 5ft 10in, with strawberry blond hair and hazel eyes.

He was wearing a grey beanie hat, blue jacket and blue checked scarf, and has a pierced left nostril.

Police began their search on Thursday, February 16.

They have now searched the building three times and were sure he was not there.

They also have his phone, which was handed into Chingford police station.

Friends set up a Facebook page called “Missing friend – Andrew Cooke”, within days of his disappearance.

Some have suggested he may have taken methoxetamine, which affects the memory.

His father, Graham Cooke, said: “It’s really hard to sit here and wait for news.

“This is the worst time because you dwell and think and come up with odd conclusions about what may have happened.

“We’re a close family and this is very tough.

“The concern is people that attended the party could be worried about getting in touch with the police but there is nothing to fear.

“They are only interested in finding Andy.”

Mr Cooke urged people to call police if they have any information. Contact 020 7232 6246 or 101.
