A man has died and four others are in a critical condition after taking a “particularly potent” form of the drug MDMA, Greater Manchester Police said. Ten people were admitted to hospital after taking the drug over the weekend, with four remaining in intensive care. Police said the drugs were known locally as “magic” or “pink champagne” and come in crystal form. A 26-year-old man, held on suspicion of supplying Class A drugs, has been released while inquiries continue. One of those admitted, a 26-year-old man from Rochdale, is died. Four men are currently in a critical condition and receiving treatment in intensive care. Three people received treatment and have been discharged from hospital. He said: “We are doing all that we can to warn people against taking the drug and help those who may have taken it. “So please, if you believe that you or somebody you know has taken the drug and begins showing symptoms then get yourselves to the hospital immediately.” He said symptoms to watch for include rigid muscles, shallow breathing, a fast-racing pulse, hyper-aggression, seizure, foaming at the mouth and unconsciousness.
