A POTENTIALLY volatile batch of drugs could be circulating in Newport.

Gwent Police have issued a warning over the issue as detectives investigate the sudden deaths of two men and two other medical emergencies.

The incidents occurred between January 1 and Tuesday this week.

It is believed the incidents were caused by the ingestion of heroin, but it is not yet clear whether they were caused by the strength of a particular batch of drugs or contamination with another substance.

Police investigating the circumstances surrounding these incidents have arrested a 31-year-old man from the Newport area on suspicion of the supply of class A drugs, following the execution of three search warrants on Thursday, January 10.

He has since been released under investigation.

Detective Chief Inspector Nicholas Wilkie, of Gwent Police's East Local Policing Area, said: "It is not clear yet whether all these tragic events are directly related. However, I cannot rule out the possibility that these deaths and medical emergencies are linked to the same batch of heroin.

"The use of heroin is, of course, illegal but I would urge anyone currently using the drug to be especially cautious and vigilant. If you are considering taking drugs - even if you are a regular user and believe you know what they are taking - please think twice.

"Anyone who believes they may have had an adverse reaction or anyone who falls ill as the result of taking drugs should seek medical attention as a matter of urgency."
