Jack Crossley, 18, suffered a fatal heart attack on 6 August (16).

His autopsy report suggests a coroner found 2.2 micrograms of MDMA per millilitre of blood - a concentration beyond what the body can safely process.

He was the second teenager to die at Fabric in a six-week period, and the tragedy prompted local council officials to revoke the club owners' licence.

As a result, Fabric was closed in September (16). It re-opened with strict conditions put in place to avoid another drug death after fans and dance music stars urged Islington Council bosses to reconsider.
