Police raiding a Christchurch property for drugs were approached by a member of the public asking to buy synthetic cannabis.
Police say they executed a search warrant at a rented residential address in Linwood at about 7am today after information was received relating to synthetic cannabis being sold from the address.
A cordon was established in the vicinity while the armed offenders squad cleared the address as the information suggested there may have been firearms at the property. The cordon was removed around 8am.
While Police Specialist Search and a police dog and handler searched the property, a member of the public arrived at the address and told plain-clothed officers they wanted to buy synthetic cannabis, Detective Sergeant Richard Quested says.
The property is divided into two flats and there were seven people at the property including a small child, he says. Some of the occupants are members of a local gang, Mr Quested says.
A quantity of methamphetamine worth $2,000 was seized by police along with a number of bags of synthetic cannabis which appeared to be packaged for sale and over $2,000 cash.
Police investigations are continuing.
