A post-mortem is due to take place today after a 15-year-old girl suddenly died in Oxford. Martha Fernback suffered a heart attack while at the South Oxford Community Centre at Hinksey Park on Saturday and was later pronounced dead in hospital.

Martha had taken a substance earlier that day which she believed was MDMA, better known as the drug ecstasy. Thames Valley Police are investigating and say the results of toxicology and histology tests will take several weeks.

A 17-year-old boy from the Oxford area has been arrested on suspicion of possession with intent to supply a controlled drug.
