ONE teenager died and two others are seriously ill in hospital after taking a quantity of painkillers.
Police said the youths, aged between 17 and 19, were found in the Sponden area of Derby.
A spokesman for Derbyshire Police said they are believed to have taken morphine sulphate, a painkilling drug also known as MST, found at the home of one of the youths still in hospital.
The spokesman said: "We are investigating the death of a 17-year-old male in Sponden.
"Early inquiries indicate he has taken a quantity of tablets.
"His death is connected to two other youths who are seriously ill in Derbyshire Royal Infirmary who have taken the same tablets."
The officer added that the 60mg tablets, which are round and orange in colour, are known to be dangerous and urged anyone who comes across them to contact police immediately.
The officer would not confirm whether the drugs were prescription, or obtained illegally.
He added: "The case is sensitive and we are unable to release any further information at this stage."
