A man, reported to be of Korean descent in his 20s, has been captured by local police as the third suspect in a fatal shooting that occurred in Sydney, Australia, earlier this month.

According to Australian public broadcaster SBS and other local media outlets on the 25th (local time), the New South Wales (NSW) Police announced that they arrested the third suspect, a 21-year-old Korean-Australian man identified as A, the previous day on charges including murder and participation in a criminal organization.

Suspect A is accused of being involved in the shooting incident that took place at a house in Merrylands, western Sydney, at around 3:15 PM on the 2nd.

At the time, a man in his 40s who suffered gunshot wounds received emergency first aid from paramedics, but died at the scene.

Local police believe that A helped the shooter move around before and after the incident and drove in another vehicle to pick up the person who disposed of the vehicle used in the crime.

An arrest video circulated on social media (SNS) shows A, wearing a gray T-shirt with the word "KOREA" printed on it, being escorted to a police station in handcuffs.

Police previously apprehended an 18-year-old man on charges of using a drone to monitor the crime scene and committing the fatal shooting.

Last week, they additionally arrested a 28-year-old woman on charges including accessory to murder and participation in a criminal organization.

Police believe that the woman acted as a lookout for the shooter and assisted in their escape.

Police are also expanding their investigation while keeping open the possibility that the suspects meticulously planned the crime but committed a mistaken-identity shooting.

According to China's state-run Xinhua News Agency, a local police official stated early in the investigation that the victim of the shooting did not live at the house where the incident occurred and had no connection to organized crime.

The official added, "Tragically, it is possible that the perpetrators shot the wrong person," noting that the residents of the house were well known to police for their involvement in organized crime.
