A string of heroin deaths in the past week has prompted police to warn about the dangers of the drug.
The deaths occurred in Stirling, Fremantle and Dianella. It is not known if they are linked to a particular batch of the drug.
There is no evidence of a “bad batch” on the street at the moment, according to a statement released by WA Police.
Det. Insp. Andrew Martin of the Serious and Organised Crime Division said police were asking those using or contemplating using drugs to be “extremely mindful of the serious consequences associated with this activity”.
“Users rarely know the purity and strength of illicit drugs and this puts them at significant risk of injury or death,” he said.
Police urge anyone with information about illicit drug distribution or use to contact Crime Stoppers on 1800 333 000.
Further information and assistance can be obtained from the Alcohol and Drug Information Service on 9442 5000 or Hopeline 1800 033 108.
