'Ecstasy' deaths: Four more arrested

Four people have been arrested following the deaths of a man and a woman in Derbyshire, who may have taken Ecstasy shortly before they died.

Officers said 15 arrests had now been made after a 20-year-old woman and an 18-year-old man were found in different flats over the same weekend.

The men aged 18, 21, 27 and 33 were arrested on Wednesday over the suspected supply of a class A drug.

Those previously arrested have been released on bail, police said.

The four latest arrests were of men from the High Peak area.

The victims were found in flats in Chapel-en-le-Frith and Eagle Parade, Buxton, on 22 and 23 December.

Detective Inspector Shaun McElheron said they had not linked the cases to date, but said there had been several other reported deaths in the North West in the last few weeks linked to ecstasy.

He said the priority of saving lives always took precedence over investigating a crime.

"Many drug-related deaths could have been avoided if the person taking drugs or their friends and family called for medical assistance", he said.
