Leah Heyes: Mum 'heartbroken' over teen's 'drug death'
The mother of a teenager who died after apparently taking ecstasy in North Yorkshire says she has been left "absolutely heartbroken".
Leah Heyes, 15, collapsed in a car park in Northallerton on Saturday night and died later in hospital.
Police believe she had taken MDMA. They arrested two teenagers on suspicion of supplying Class A drugs, but released them under investigation.
Leah's mum, Kerry Roberts, paid tribute to a "much loved and thoughtful girl".
"Leah was my best friend," she said.
"She was a thoughtful, beautiful girl, who was much loved.
Ms Roberts described her daughter as "fun, bubbly" and said she had "a great sense of humour".
"I'm absolutely heartbroken to have lost my beautiful girl," she said.
"No words can describe how much she will be missed and the enormous gap she has left in our lives.
"She will be truly missed more than words can say. I love you always."
Emergency services were called to Applegarth car park at 21:30 BST.
Leah, who was from Northallerton, was taken to hospital in Middlesbrough where she later died.
An 18-year-old man was arrested on Monday, after officers detained a 17-year-old boy.
North Yorkshire Police said it had "not ruled out making more arrests".

The force has appealed for anyone who has mobile phone footage taken on the night to come forward.
It said about 20 people were in the Applegarth area on Saturday night and officers needed to "speak to all of them, and anyone else who was passing through".
Det Insp Eamonn Clarke said: "Inquiries also reveal that there may be mobile phone video footage of the events of that tragic evening.
"This footage will be extremely helpful to our investigation."
He said the teenager's family were "devastated and a community left in shock".
"It is vital that people come forward and help us find the answers for Leah's family and friends," he added.
