Officers from the Swindon Community Policing Team arrested a man and woman from London on suspicion of class A drug supply in Swindon Friday morning.
Shortly after midnight, officers attended an address in Akers Way and carried out a search of a property.
A quantity of class A drugs, believed to be heroin, was located inside the property.
An 18-year-old man and a 29-year-old woman both from London were arrested on suspicion of class A drug supply offences.
They remain in custody at Gablecross.
Detective Constable George Booth, of the North Dedicated Crime Team, said, “Officers attended this address following information reported to police by concerned members of the public that ‘cuckooing’ was taking place. Drug dealers will often take over the homes of vulnerable people to use as a base to deal their drugs which is known as cuckooing.
“We are urging members of the public to look out for their neighbours and if you have noticed more people calling at an address than usual, and often at unsociable hours, or you’ve noticed strange smells, vehicles or people at an address, to report it to police via 101 as cuckooing could be taking place.
“We are committed to protecting the most vulnerable people in society and need the public to act as our additional eyes and ears in order to disrupt drug supply within our communities.”
Call 101 to report information, or call Crimestoppers anonymously on 0800 555 111.
