A young woman has died after her drink was allegedly spiked at a Christmas party.
Gemma Thomas, 26, was laughing and joking with friends when she suddenly collapsed.
Party-goers called an ambulance and Gemma spent four days in a coma before dying in the Royal Glamorgan Hospital in Llantrisant.
South Wales Police are investigating claims her drink had been laced with heroin substitute methadone at the house party in Graigwen, Pontypridd.
Two men were arrested on suspicion of supplying the drugs after Gemma collapsed at a house.
She was treated in intensive care but never regained consciousness.
Doctors told her family Gemma would never recover and they agreed to switch off her life-support machine.
Gemma’s parents Wayne and Jacqueline were too upset to comment but one of her close friends said: “She was a great girl and liked a drink and a party – but she never touched drugs.
“There’s no way she would have taken anything voluntarily, she just wasn’t like that.
“She went to a party to get into the Christmas mood – but we’ll never see her again.”
Police have interviewed fellow party-goers over the tragedy.
Her boyfriend Jason Hay, 43, was yesterday described as being “devastated” at her death.
Mr Hay was being comforted by relatives at his mother Margaret’s home in Heol Waun, Tonyrefail.
Mrs Hay, 66, said: “We’re all devastated. Gemma was a lovely girl.”
A police spokesperson said: “An officer responded to an emergency call at 11.30pm after concerns were raised about a 26-year-old female’s wellbeing.
“Police are investigating the circumstances surrounding the incident and two local men have been arrested.
“They were bailed pending further inquiries.”
Glamorgan Valleys coroner’s officer Stuart Griffiths said a post-mortem examination is due to be held on Tuesday.
