Three further suspected drugs deaths are being investigated in Barnsley, police have revealed.
It comes after a series of deaths believed to be linked to a contaminated batch of heroin in the town as well as the wider region.
Suspected drugs deaths have also been reported in other areas of South Yorkshire and West Yorkshire in recent weeks.
A total of seven deaths are now being investigated in Barnsley alone - the most recent reported on Wednesday, while two others were reported in late April.
Previous warnings issued across the Yorkshire and Humber region indicated that batches of heroin may have been contaminated with Carfentanyl and another substance called Fentanyl.
Fentanyl is an anaesthesia used to help prevent pain after surgery or other medical procedures and is 100 times more potent than street heroin.
Carfentanyl is extensively stronger than Fentanyl and is used on animals.
Officers in South Yorkshire are working closely with investigative teams across the Yorkshire and Humber region to piece together the information we have gathered as part of our enquiries into this series of incidents.
