Middlesbrough drugs alert: Six treated after taking 'strong' ecstasy
Police have issued a warning about a batch of ecstasy tablets after six people were treated in hospital.
The tablets, which police said had higher than usual levels of MDMA - the base chemical of ecstasy - were taken at a Middlesbrough bar on Saturday.
All of the tables carry a distinctive "UPS" logo.
Cleveland Police said none of those affected had suffered any serious injuries, but that such drugs were "potentially lethal".
