Tests on the body of an 18-year-old man who died after he fell ill at a weekend rave have proved inconclusive, police said last night.

The unnamed clubber had been at the Godskitchen all-night party at Newcastle's Telewest Arena which attracted a sell-out crowd of 7,500 people.

The teenager was a shop assistant who worked in the city and came from the Tyne Valley, police said, adding that he would not be named until his relatives had been informed.

An inquest was likely to be held into the man's death in Newcastle later tomorrow.

A Northumbria Police spokeswoman said: ''A post mortem examination has proved inconclusive and we are awaiting the results of toxicology tests.''

The man was taken to Newcastle General Hospital by ambulance early on Sunday and was pronounced dead on arrival.

Police sealed off the indoor arena which stands on the banks of the River Tyne and have now finished their examination of the scene.

Other inquiries into the death will continue today.

The arena is also home of Newcastle Jesters ice hockey team and tonight's match against Basingstoke wascancelled due to ''unforeseen circumstances'' telephone callers to the venue were being told on a recorded message.

The arena management issued a statement saying Godskitchen organisers have organised parties internationally for five years, and this was the first serious incident associated with the event.

It said: ''It is with great sadness that Telewest Arena confirms that a patron of the Godskitchen dance event, which took place from 9pm on Saturday to 6am on Sunday, has died in hospital.

''Safety is of paramount importance to all events held at the Telewest Arena and this is the first time a serious incident of any kind has occurred.

''Godskitchen organisers further confirmed that this is the first time an incident of this kind has occurred at one of their events, which have been operating successfully for five years.

''We are currently liaising closely with the police in an effort to clarify the circumstances surrounding this fatality.''
