Police have issued a warning to heroin users following the sudden death of man.
The 26-year-old was found dead at an address in Bank Avenue, Morley, Leeds, at about 1.30pm on Sunday after an ambulance was called to the scene.
A post mortem examination proved inconclusive and the results of toxicology tests are awaited to establish the cause of his death.
Detective Inspector David Roberts, of Leeds District CID, said: “Work to establish the cause of this man’s death is ongoing but it is known that he was a heroin user and had been taking drugs in the time leading up to his death.
“It is not yet known if the strength of the heroin taken was a factor or if the heroin had been cut with something unusual, but the police and public health officials feel it is appropriate to advise drugs users that if they feel unwell or get an unusual reaction to something they have taken, they should seek medical advice immediately.”
Three men, aged 30, 42 and 58, were arrested on suspicion of drugs offences in connection with the man’s death and were later released on police bail pending further enquiries.
