A man succumbed to his injuries at the hospital after being discovered with stab wounds on Talisker Gate in Aubin Grove around 10:40 p.m. on Christmas Eve.

Authorities have now charged a 17-year-old and an 18-year-old with murder, deprivation of liberty, and aggravated armed robbery in connection with the incident.

The two accused individuals are scheduled to appear in court today, with the teenager facing the Perth Children’s Court and the adult appearing in Perth Magistrates Court.

This brings the total number of males charged in relation to the stabbing to three.

An 18-year-old was previously detained and also charged with murder earlier this week.

He faced the Perth Magistrates Court yesterday, where he was remanded in custody until his next court appearance on January 7.

Police will allege the trio were fighting the 19-year-old man inside and outside a car on Talisker Gate when he was stabbed several times.

It is believed to be an isolated incident, and police are not searching for anyone else.
