BLUE 'punisher' pills have been confiscated from festival-goers at this weekend's Parklife.

Organisers have tweeted out a warning about the ecstasy pills which are potentially lethal.

They also shared photos of the triangular pills which have been placed in a confiscation box.

In a further tweet, Parklife organisers said they had been made aware of a brand that was handing out contraband sweets.

They warned that this could lead to additional security checks on the gates.

In the run up to the event, Parklife warned against the circulation of the blue 'punisher' pills after two young people died.

Georgia Jones, 18, and Tommy Cowan, 20, collapsed at the Mutiny Festival in Portsmouth on Saturday May 26.

The pair, who fell ill 20 minutes apart, died amid reports of a ‘high strength or bad batch’ of drugs at the event.

After testing the substance, the drug awareness non-for-profit company The Loop found these pills to have “a strength above 330mg” - almost four times the amount of MDMA found in a typical ecstasy pill.
