Two found dead in Bolton after taking 'contaminated amphetamine' 28 April 2013 Last updated at 23:39 Two people have died after taking what police believe to be a contaminated batch of amphetamine. Both victims are thought to have taken the drug before being discovered separately at different addresses in the Bolton area. Officers discovered the body of a 21-year-old woman in Buttermere Road, Farnworth at 13:30 BST on Sunday. A body of a 30-year-old man was discovered at a house in Littlebrooke Close, Tonge Moor half an hour later. Post-mortem examinations and toxicology tests have not yet taken place. Hospital check-ups urged Det Insp Michael Sanderson of Greater Manchester Police said: "From the information we have received, we believe both may have taken amphetamine. Although we cannot say this was the cause of death until toxicology tests are complete, we are concerned there may be a contaminated batch of drugs in the area. If anyone has recently taken drugs and feels ill, I would ask you to go to hospital for a check-up. I would always advise people not to take drugs, as you do not know what it has been mixed with and you are getting what you pay for.
