A dangerous new drug on the streets of Folkestone is being used by teenagers as young as 15, police have warned.

The blue pills, known as rockstars, came to light after a 15-year-old boy from the town was arrested on suspicion of possessing a drug with intent to supply this week.

He has been released on bail pending further investigation.

The pills have an R or star logo and it is understood that they are selling for up to £10 each.

Drugs officer for Shepway PC Jeff Treadwell said: "We are very concerned that these pills are being used by the 15 to 18-year-old age group.

"Tests are being carried out to establish what they contain but adverse reactions ranging from severe stomach pains resulting in hospital admissions to excessive teeth grinding have been reported."

It is not known whether the blue pills are linked to red rockstars - believed to be a type of ecstasy, which is suspected of causing the death of a 25-year-old in County Durham on Sunday.

PC Treadwell added: "We do not know what these pills are but neither do those taking them and this again highlights the danger of so-called recreational drug use.

"We have already contacted schools and once pupils return after the half-term holiday we shall be going in to talk to highlight the risks they may be taking."
