Meet Sydney's 'baby formula gang': Asian family-of-four is accused of stealing $1MIILLION worth of powder from Coles and Woolworths to sell to wealthy Chinese buyers

• Family accused of masterminding theft of over $1million worth of baby formula
• A 31-year-old man detained at Sydney Airport after arriving on flight from China 
• In August, investigators raided two homes in Carlingford and seized 4,000 tins
• The man's parents and sister were arrested in August and since been charged 

A family that runs a Sydney newsagency is accused of masterminding the theft of more than $1million worth of baby formula and exporting it overseas.  

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.

His parents, Lie and Wueqi Ke, as well as his sister Xiaoyu, 29 were previously charged over their alleged roles in the syndicate.  

The 31-year-old, named by the Daily Telegraph as Jian Feng Ke, was charged with dealing with the proceeds of crime and participating in a criminal group. 

He was granted bail before he unsuccessfully applied to have a curfew lifted so he could continue to work at the Carlingford newsagency in the city's north-west, the paper reported.  

In August, investigators from Strike Force Dungv raided two homes in Carlingford and seized 4,000 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.

Robbery and Serious Crime Squad Commander, Detective Superintendent Daniel Doherty, praised the work of Strike Force Dungv investigators.

'This has been a meticulous investigation, with detectives now putting five people before the courts and disrupting a well-coordinated theft syndicate,' Det Supt 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.'

Investigations under Strike Force Dungv continue.
