A TEENAGE girl who died after apparently taking ecstasy has been named by police as Leah Heyes, from Northallerton.

North Yorkshire Police has also revealed that a teenage boy has been arrested on suspicion of being concerned in the supply of class A drugs - and says further arrests are possible.

The 15-year-old died in hospital after collapsing in the Applegarth car park in Northallerton on Saturday evening.

A force spokesperson said officers were continuing their investigation into the circumstances that led to her tragic death.

"A post mortem is due to be carried out to determine the cause of her death," they said.

"We believe that Leah had taken the drug MDMA - also known as ecstasy or a "bomb" - prior to collapsing and we reiterate our warning to anyone who uses drugs, of the potential consequences.

"At this stage, one teenage boy has been arrested on suspicion of being concerned in the supply of class A drugs.

"However, officers have not ruled out making further arrests as the investigation continues.

"We urge anyone who was in the area at the time or has any information about the events on Saturday night, to come forward and speak to the police if they have not already done so."

Anyone with information should phone 101, select option 2 and ask for Northallerton CID, or pass information anonymously to Crimestoppers on 0800 555 111, quoting reference number 12190085105.
