Two people are in hospital after taking drugs from a "potentially fatal" batch of ecstasy, police have said.

The clubbers, 23 and 18, were taken ill at Fabric nightclub in Clerkenwell, central London, over the weekend.

The 23-year-old, of Stanmore, whose gender has not been revealed, is in a critical condition, while the 18-year-old man is stable, police said.

Det Supt Adrian Usher said: "Users need to be aware that a potentially fatal batch of ecstasy is out there."

He added: "We know they had taken ecstasy and that this batch of drugs could be available in other locations across London.

"Drug-dealers are only interested in making money so users can never be really sure what they are taking.

"I strongly advise people to be cautious and if they have purchased any ecstasy recently to destroy it."

A spokesman for Fabric said the club had a zero-tolerance drugs policy.
