Detectives have confirmed they are investigating links between the death s of three men in Kirklees.
They believe all are due to drugs and tests are now being carried out to confirm if a potential ‘bad batch’ of heroin could be a cause.
The identities of all three men have now been released and it is believed two of them are related to each other.
Scenes of crime and forensic invesigators joined police at the scene for much of Thursday.
His death comes just weeks after a man was found collapsed in Dewsbury Market Hall on November 14 and later died in hospital.
He has since been named as Jamie Barlow and is believed to be Trevor’s nephew.
The other victim was 51-year-old Phillip Holderness, who also died on November 28 at his home address in Dewsbury town centre.
All three deaths happened within a half-a-mile radius in Dewsbury.
Det Insp Andy Parr of Huddersfield CID said: “We are investigating three recent drugs deaths.
“Obviously it’s dangerous to take drugs in any event and there is always a risk with these kind of offences.
“There is no indication that there was a bad batch of heroin but as with any drugs death, toxicology will now map the result.”
Chris Lawton, adult service manager at Lifeline Kirklees, who works with drug users, said: “Our sympathies go out to the families, and communities affected by these deaths.
“We urge anyone that is using, or contemplating using, substances to come forward to services so that we can talk to them about their use.
Police confirmed test results could take at least two week.
All three deaths have been referred to Dewsbury Coroners.
Anyone with information should contact Huddersfield CID on 101.
