A British teenager on holiday in Ibiza has died after what is suspected to be an ecstasy overdose, according to authorities. Danielle McCallum, 18, from Greenock, Renfrewshire, was staying at the party resort of San Antonio.

She was rushed to a health clinic close to her hotel, and later taken to the Can Misses Hospital, where she was being treated in the intensive care. McCallum suffered heart failure at the hospital and was later pronounced dead on 22 September.

"I can confirm an 18-year-old British woman was admitted to Can Misses Hospital at 4am yesterday/on Tuesday [22 September] following suspected MDMA consumption," said a spokesman for the Can Misses Hospital, reported MSN. "She was admitted to the hospital intensive care unit in a critical condition and two hours later died from heart failure."

An autopsy scheduled to take place on 23 September will confirm if McCallum's condition was indeed triggered by an overdose of drugs. While the autopsy is expected to reveal only partial results, further analysis will take place at a specialist lab in Barcelona.

Meanwhile, a foreign office spokesman said: "We are in contact with local authorities in Ibiza following the death of a British national on September 22. We have met with the family and will continue to provide support at this difficult time."

An investigation is currently underway, confirmed a spokesman for the Guardia Civil. Social media users shared their thoughts on the tragic death of McCallum.
