POLICE have issued a drugs warning in West Yorkshire over a batch of so-called 'Superman' ecstasy linked to the deaths of four people elsewhere in the country.

Officers say there is no specific reason to believe it is being sold in this area, they are warning users of the danger associated with the drug, which is distributed as a red tablet with a Superman logo stamped into the surface (pictured).

Bryan Dent, West Yorkshire Police's Drugs Coordinator, said: "Provisional forensic tests from the Suffolk investigation indicates the tablets that led to the deaths contained a particularly harmful and dangerous ingredient (PMMA). This is more likely than usual to cause harm or even death to anyone taking the drug.

"Users of any drug can never be really sure of the contents of anything they take but with ecstasy, which is a class A drug meaning it's illegal to possess and supply, the potential health issues are very real and potentially fatal."
