Two Cambridgeshire men have died within 24 hours after apparently taking ecstasy-type pills.
The tragic events have prompted a police warning about the potentially-lethal drug.
One man, who was in his 20s, died after falling ill at a property in Huntingdon, shortly before 4am today.
His death came a few hours after police were called to an address in Westwood, Peterborough, where another man, also in his 20s, died.
Neither death is being treated as suspicious, but searches are taking place at the two properties and an investigation is taking place into the supply of drugs in the area.
Detective Inspector John McAdam said: “While we still have to await the results of further tests to ascertain exactly howthese two men died, it appears they may be linked to the use of drugs.
“I would urge people to be extra vigilant and not take illegal substances, in particular ecstasy-type pills because they could have grave consequences. There is no knowing what such pills contain and what effects they may cause.
“If you are offered any such drugs over the long weekend or have any information about the supply of drugs in Peterborough or Huntingdon, please call police.”
The warning follows a similar death in Bournemouth on May 21.
Information can be given to police on 101 or to Crimestoppers on 0800 555111. Drug advice is also available from FRANK on 0800 776600.
