Five people have been charged over allegations a crime syndicate has been conducting the “well-coordinated” theft of more than $1 million worth of baby formula across Sydney.

The latest arrest came on Saturday, when a 31-year-old man was detained at Sydney Airport after he arrived on a flight from China.

The Carlingford man was charged and appeared at Parramatta Bail Court on Sunday, where he was granted strict bail. He will reappear at Parramatta Local Court on January 30.

In August, investigators from Strike Force Dungv searched two homes in Carlingford and seized 4000 tins of baby formula, large quantities of vitamins, and Manuka honey; all of which were allegedly stolen. They also seized more than $215,000 in cash, allegedly the proceeds of crime.

A 48-year-old woman and a 35-year-old man were charged at that time and remain before the courts. Another man, 53, was arrested on December 19 and a 29-year-old woman on January 4.

Police will allege in court that the two men and woman were part of an organised syndicate receiving more than $1 million worth of stolen products, including baby formula and health supplements, which were then on-sold overseas.

Police said the five accused were part of a “well-coordinated” crime syndicate.

“This has been a meticulous investigation, with detectives now putting five people before the courts and disrupting a well-coordinated theft syndicate,” Detective Superintendent Daniel Doherty said.

“Police will continue to pursue those who seek to make a quick buck at the disadvantage of others and will always strive to stamp out unscrupulous activity.”
