There were further searches on Thursday by the drug detection dogs at residences in Norfolk Street Nobby; Murilla Street, Clifton and East Street, Clifton. Two men and two women will appear in the Warwick Magistrates Court on charges of possessing dangerous drugs and drug utensils.

The operation continued Friday with five Warwick residents issued court appearance notices for matters relating to offences against the Drugs Misuse Act.

A 30-year-old man was arrested on amphetamine drug supply charges at a Deighton Street address and was remanded in custody to appear in court over the weekend.

Major and Organised Crime Squad (Rural) Investigator, Senior Constable Jim Doyle, said with the support of specialist police units, including the Dog Squad, police would continue to target criminal groups attempting to conduct illegal business in our region.

"The cultivation and manufacture of illegal drugs will not be tolerated and those caught supplying these substances in our communities will be put before the courts," he said.

"We will also maintain a focus on the illegal or unlawful possession of firearms, which may be used to commit violent crimes and put the safety of our community at risk."
