A female clubber who collapsed after taking a dodgy dose of class A drugs has left hospital.

The woman, in her 20s, had taken MDMA - a form of ecstasy - at Fabric nightclub, in Charterhouse Street, Farringdon, and became seriously ill in the early hours of Sunday morning.

Police rushed to the world famous venue at 5am and the victim was taken to hospital.

Her condition was initially assessed as critical, and officers were attempting to contact her next of kin, but she recovered and has now been discharged.

Islington police have issued a warning about the bad batch of the drug.

A spokesman said: “Officers are keen to make the public aware that there may be an increased risk of adverse effects from this batch of MDMA taken by this female.”

The incident comes after the Fabric’s owners were pulled in front of Islington Council’s licensing committee following two drug related deaths at the venue in the space of just a few months.

The club was allowed to keep it’s licence and more than 40,000 people from all around the world signed a petition to save the night spot as long as strict conditions - such as sniffer dogs on the doors for 50 per cent of events - were imposed.

However the club have contested the council’s decision, meaning the new rules don’t have to be implemented until the appeal hearing in December.
