COPS have issued a warning after a dangerous batch of Green-Rolex-type pills were discovered at T in the Park – just days after two teenagers died at the festival.

Police said on Sunday they discovered a small batch of the green pills which are stamped with a Rolex crown.

In statement they said: “Police Scotland has recovered a small number of Green Rolex-type pills at T in the Park and is warning festival goers to beware of any others that might be in circulation.

“Pills similar to these have caused serious harm in the past although there is no evidence at present to link these to any other incidents at the festival.

“People are reminded there is no safe way of taking drugs and T in the Park has a zero tolerance drugs policy.”

Police Scotland also said the drugs had similar characteristics to Green Rolex which was in circulation in 2012 and 2013 and linked to several deaths across the UK.

 A Police Scotland spokesman said: "Following a single recovery of a small quantity of Green Rolex pills, the public were informed that these tablets were in circulation. 

"The pills shared similar characteristics to tablets recovered in 2012 and 2013.

"However there is no evidence at present to link to other incidents at the festival."

The discovery comes as investigations continue into the deaths of tragic 17-year-old Peter MacCallum from Lochilphead, Argyll and Megan Bell of Seaham, Durham.

Megan took ill in the festival’s Slam tent on Thursday night and despite being taken to a medical centre by her friends, she died soon after.

Meanwhile, Peter was found unconscious in a tent a few hours later before being pronounced dead by medics at 5am.

Police said potential drug use was one line of inquiry they were investigating over the deaths of the teenagers.

On Saturday, T in the Park organisers urged anyone with drugs at the festival to dump them in special bins around the site.

They also people who got rid of their drugs would not get into trouble.
