Police have charged a second alleged “kill crew” today over the kidnapping and murder of an organised crime network member’s wife in Sydney last year.

Thi Kim Tran, 45, was at her home in Bankstown about 10.30pm on April 17 when a group of men allegedly forced their way in and kidnapped her at gunpoint.

The men are accused of assaulting an eight-year-old boy with a baseball bat, putting him in a coma, before forcing the woman into an SUV.

A 15-year-old boy also present during the home invasion was taken to hospital for assessment.

About an hour later, a car was found burning on Welfare Avenue in nearby Beverly Hills.

Fire crews extinguished the blaze, but the car was destroyed and police found Tran dead inside.

Police allege the woman was likely targeted due to her husband’s involvement with a Victorian-based organised criminal network.

Four have been previously charged and remain before the courts.

Detectives will allege a second “kill crew” were waiting at a rural property in Victoria for Tran’s husband with the intention of killing him.

When he failed to appear, Sydney-based offenders allegedly kidnapped Tran in a bid to force his compliance, before ultimately killing her.

Since last December, five others have been charged over their alleged role in Tran’s abduction and murder.

On December 16, police arrested a 26-year-old man following a raid on a property in Monterey in southern Sydney.

Later on January 16, detectives arrested a man aged 22 at Sydney airport before they took into custody a 30-year-old man at the same location on February 21.

On March 16, two men – aged 18 and 25 – were arrested in Silverwater and Lithgow.

All were refused bail and charged with murder, firearms offences and participating in criminal group activity.
