Police said overdoses have risen in past 10 days
Police in Swansea are warning drug addicts to seek advice following a spate of overdoses and a fatality attributed to heroin.
Detectives are investigating whether the incidents over the past 10 days are linked to unusually high purity drugs.
Heroin users are being advised to contact drug agencies or their GPs for advice on how to stay safe.
Meanwhile officers say they are making arrests on a 'daily basis' to combat the supply of hard drugs in the city.
Acting Superintendent Peter Azzopardi said: "Over the past few days we have had a number of overdoses initially attributed to heroin as well as one death.
"I am urging individuals who are dependent on this type of substance to think twice about what they are taking and seek advice from their GP or one of the substances misuse agencies who will also give advice on how to stay safe.
"It is unclear at present as to whether this is to do with purity or some other reason and further information will be released if this can be established."
He said enforcement operations were taking place across Swansea on a daily basis, often as a result of information from the public.
Mr Azzopardi added: "I would like to thank those members of the Swansea community who care enough to help us in our endeavours by supplying us with information.
"I would like to reassure them that the information is acted upon and quite often is the missing link which turns information into intelligence worthy of action."
