Four men have been charged with the organised theft of shipping containers, trucks and freight trailers following a major police sting in western Sydney.
Detectives have been investigating a number of commercial thefts, including that of a prime mover and side loader from two properties at Chipping Norton on Saturday night.
Hours later, the same vehicles were allegedly used to remove two trailers carrying shipping containers which contained tyres worth $150,000 from a property at Eastern Creek.
On Tuesday, police executed a search warrant at Austral and recovered a number of the items stolen at the weekend.
They also seized a truck previously reported stolen, and breaking tools.
About 9am (AEDT) on Wednesday officers raided seven homes and properties in Granville, Guildford, Auburn and Old Guildford.
Four men were arrested and various items of property seized, including a Mercedes sedan and Toyota four-wheel-drive, a boat, a pistol, a stun gun, breaking tools, electronic items, steroids and documents.
A 25-year-old man arrested at Granville has been charged with 22 offences, including aggravated break and enter, larceny, stealing a motor vehicle and dealing with the proceeds of crime.
A 20-year-old man arrested at Auburn has been charged with six offences, including aggravated break and enter and participating in a criminal group.
They were both refused bail to face Burwood Local Court on Thursday.
A 24-year-old man arrested at Guildford has been charged with 19 offences, including fraud, while a 19-year-old man arrested at Old Guildford was charged with 14 offences, including aggravated break and enter, and dealing with the proceeds of crime.
Those two men were refused bail to face Fairfield Local Court on Thursday.
Police said their investigations were ongoing.
