Qld police charge 4 after anti-bikie sting

Police claim they've disrupted the supply of methylamphetamine in southeast Queensland after charging four men in a year-long operation.

The men include three with alleged links to criminal bikie gangs.

They were arrested and charged following the execution of seven search warrants at properties across the southeast.

Codenamed Operation Lima Bordeaux, the investigation was focused on bikie gang activity at Ipswich, west of Brisbane.

Police allegedly seized methylamphetamine, cannabis, drug manufacturing equipment and two replica handguns during the raids which occurred at properties in the greater Ipswich region, the Gold Coast and Calamvale.

An alleged former member of the Comancheros gang, who is also accused of being an associate of the Bandidos, has been charged with drug trafficking and unlawful possession of concealable weapons.

Two other men, who are alleged to be Bandidos members, have also been charged, one with receiving tainted property, the other with possessing dangerous drugs.

The fourth man is accused of producing, trafficking and possessing dangerous drugs.

The operation was a joint operation between Ipswich criminal investigation branch officers and detectives from the Taskforce Maxima operation, which is targeting criminal motorcycle gangs and their networks across Queensland.

AAP is seeking confirmation a grenade was located at one of the properties raided, reported to be a storage facility in the suburb of Raceview.

Reports claim the bomb squad has been called to the location, where police allege a storage shed was being used as a drug lab.
