They were reportedly enjoying a night out with a larger group, who are also believed to have taken the substance, though noone else in the group appears to have suffered any ill-effects.

Devon and Cornwall Police are investigating the deaths. Detective Inspector Julie Scoles told Sky News: "It is currently believed that the two men who died were part of a larger group who had taken what they thought to have been MDMA.
