Detectives have smashed an international crime ring accused of stealing more than one million dollars worth of luxury items, jewellery and cash from a number of Sydney homes and designer stores.

Police in November investigated 80 aggravated break-ins across Sydney throughout September and October which led them to the activities of an organised theft gang also accused of shoplifting at designer Sydney stores.

Five men and three women, all Chilean nationals, allegedly broke into homes in Vaucluse, Rose Bay, Five Dock and Castle Hill and stole $1.2 million worth of jewellery, luxury items and cash.

Police allege the group also stole luxury items from designer stores across Sydney before allegedly shipping all the items and cash overseas.

NSW detectives worked with Chilean authorities to seize packages believed to contain the stolen items.

The group is facing a string of break-in and shoplifting offences.

Two men aged 23 and 27 were nabbed at Sydney International Airport and refused bail to appear at Central Local Court on January 22.

A 36-year-old woman and two men aged 22 and 29 were arrested at a Sydney Olympic Park unit. They were refused bail to appear at Burwood Local Court on January 23.

Police arrested a 41-year-old woman at a Leppington home who was refused bail to appear at Central Local Court on January 22.

A 34-year-old man and 19-year-old woman allegedly involved in the syndicate were arrested in Melbourne with NSW Police expected to seek their extradition.

Detective Superintendent Daniel Doherty called on people to come forward if they have any information and urged residents to properly secure their homes and cars.

“This has been a sophisticated and meticulous investigation; spanning not just across Australia but across the Pacific Ocean,” Det Supt Doherty said in a statement on Friday.

“We want to hear from anyone who may have information that can assist us in dismantling this syndicate.”
