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".
