REVELLERS could hold vital clues to the death of a teenager who collapsed in a nightclub, say police.

Garry Henderson, 18, was taken ill at the New Monkey nightclub, in Pallion Road, Sunderland, at about 6am on Sunday.

The teenager, from Cambridge Street, Cruddas Park, Newcastle, was taken by ambulance to Sunderland Royal Hospital, where he was pronounced dead.

A post-mortem examination was carried out yesterday.

Further toxicology tests will follow, looking at whether or not drugs were involved.

Police last night urged other clubbers to speak to them in confidence.

The nightclub, a former cinema and bingo hall, was sealed off yesterday, along with the neighbouring Steels Social Club.

People living nearby have long campaigned for the New Monkey to be closed, complaining about noise and anti-social behaviour.

Mr Henderson was wearing a grey Rockport jacket, a blue and white Henry Lloyd T-shirt, navy blue Adidas tracksuit bottoms and white Nike trainers.

Anyone who saw him in the club or has other information, is asked to contact police on 0191-454 7555.
