A VIGIL has been staged in memory of a 15-year-old girl, a week after she died after taking ecstasy.

Leah Heyes, 15, collapsed near a playground in Northallerton on Saturday evening last week and died later.

North Yorkshire Police has said the cause of her death was still to be determined, but she had taken MDMA, also known as ecstasy or a 'bomb', prior to her collapse.

The mother of Leah Heyes has thanked people for coming together in the town last night to remember her daughter.

Kerry Roberts said:"I would like to thank everyone for all of the kind messages and tributes following the death of my beautiful daughter Leah.

"I’m overwhelmed with the support that people have shown.

"Thank you for coming together to remember Leah tonight, it’s such a fitting tribute to her as she loved to be around people and to spend time with her friends.

"She would be really happy to know that you all cared so much about her."

North Yorkshire Police said a 17-year-old boy and an 18-year-old man who were arrested on suspicion of being concerned in the supply of class A drugs remain released while under investigation.
