Drugs alert: Police have issued a warning about cocaine and heroin. Picture: Press Association

Police are warning drug users and the street community about the drugs.

In a couple of cases the cocaine found to have been taken was nearly 100 per cent pure.

Now police have issued a warning through the drop-in centres for drugs users and the street community to beware of the ‘bad batch’ of drugs in circulation on the street.

Detective Inspector Neil Ralph said, “Since April there have been a number of drug overdoses in the town and two drug-related deaths.

“We investigate all drug overdoses and drug-related deaths and look to identify who has supplied the drugs and seek a prosecution.

“This can be difficult at times because it is often the case the only person who knows the source of the drug is deceased.”
