Speaking of the incident, Det Insp Brian Morley said: "These women are very lucky. I'm happy to be saying they should make a full recovery, but the reality is, I could easily have been giving my condolences to their families instead."

The news follows on from an earlier report last week, 3 May, where 17-year-old girl, Faye Allen, died after taking a so-called 'Mastercard' branded tablet at the Victoria Warehouse nightclub space, based in the Trafford area of Manchester, according to another report by the BBC.
