Police have carried out a number of raids across southern Queensland as part of an operation targeting outlaw motorcycle gangs.
Officers from Taskforce Hydra raided properties in Toowoomba, Charleville, Goondiwindi and Roma this morning, searching for cannabis and methamphetamine.
Police say a handgun, cash and an amount of illicit drugs were seized.
It is not clear if anyone has been arrested.
The action brings to a close Operation Kilo Agitator, which began in southern Queensland last year.
Detective Inspector Garry Watts from Taskforce Hydra says the raids are a culmination of work between local police and the taskforce to stamp out the trafficking of illegal substances by bikie gangs.
