Two deaths in the city have been linked to heroin use

Strathclyde Police said the deaths in Milton appeared to be linked to heroin, although there was currently nothing to suggest a bad batch was in circulation.

Police are waiting for toxicology test results and further tests are being carried out.

Det Supt Willie Prendergast said users should take the necessary precautions.

'Inherently dangerous'

"I would urge people who insist on taking illegal drugs to take the necessary precautions to make sure they are safe, such as making sure they are not alone when using heroin," he said.

"There is also a need to reinforce the message that taking any type of illegal drugs is inherently dangerous and frequently results in the death of the drug abuser.

"Should drug users wish more information in relation to reducing their exposure to risk, we would urge that they seek that advice from health professionals."

Police issued the warning on Sunday after two deaths in the city since Friday.

Strathclyde Police will be speaking to its partner agencies including health workers, social work and alcohol and drug action teams to alert drug misusers to the potential health risk.
