A schoolgirl was dumped unconscious and frothing at the mouth by friends after taking MDMA, her mum has claimed.
The teen took the drug, also known as "pingers", before she became unresponsive according to the concerned mother's post on Facebook.
The 15-year-old was said to have been dragged along a road in Tidworth, Wiltshire, on Saturday night, but was left by her friends after they were spotted police officers.
Her unnamed mum says she was told by police they initially "thought her child was being kidnapped because her so called friends were dragging her across the street."
The girl is still in hospital but "doing well" but wanted to warn other parents of the dangers of drugs.
The post read: "Calling all parents beware there is a drug going around Tidworth and surrounding areas a pill that the teenagers call pingers.
"She was lucky and was found at the right time by police officers. She was found unconscious and foaming at the mouth!
"Please please have a word with your teenagers express again the dangers of drugs, and instead of trying to drag a friend or hide a friend that is clearly not doing well call 999 don’t be scared of getting into trouble, this is someone’s life.
"This happened on Saturday night in Tidworth and if the police hadn’t happened to come down Station Road at that moment and see these group of teenagers dragging my daughter she wouldn’t be here today!!!
"She is still in hospital but doing well she feels very stupid and ashamed for being so stupid and thinking it’s cool to fit in with crowd.
"But more disappointed so that her friends were more worried about getting into trouble rather than calling 999 to help her!!
"She has learnt a big lesson this weekend the hard way! Don’t let this happen to your child."
The Mayor of Tidworth, Councillor Mark Connolly, urged anyone with information to contact police.
He said: "I have seen various Facebook posts about the horrible incident over the weekend where a young lady became seriously ill after having taken a pill.
"The actions of the young lady's so-called friends involved in the incident are reprehensible and they should be ashamed of themselves.
"I have contacted the family to wish the young lady a speedy recovery.
"I have also contacted the local police inspector about the incident.
"Whilst he could not go into the specifics of the investigation, he assured me that drugs is a very high priority for the police and that much of their work in this area goes unseen.
"If anybody knows about this incident or wishes to provide other information about drugs or drug dealing in the town, please ring 101 or report it on the Wiltshire Police website, so that they can take action against the people who are putting young lives at risk.
"Anyone with information relating to this incident is asked to contact Wiltshire Police by calling them on 101. Alternatively, you can call Crimestoppers anonymously on 0800 555 111."
Wiltshire Police have been contacted for comment.
