Pilbara police have arrested 10 people after a series of drug busts.

Officers from Onslow police, Karratha detectives and Pannawonica police last week searched several Onslow residences.

A total of 35 criminal charges were laid, including selling or supplying of prohibited drugs, with officers seizing methamphetamine, cannabis, drug paraphernalia and unlicensed ammunition.

Onslow police said they would continue to fight the battle against illicit drugs and encouraged the community to co-operate with police.
