Teen arrested near Bunbury over alleged mass shooting threat against Sydney mosque

A 16-year-old boy has been charged after he allegedly made a threat of a mass shooting at a Sydney mosque.

The Australian Islamic House Masjid Mosque in Edmondson Park alerted police after they allegedly received a comment on their Instagram page which said  "I'm going to christ church 2.0 this joint".

The comment appears to reference the 2019 Christchurch mass shooting where Australian-born Brenton Tarrant stormed a mosque and killed 51 people.

NSW Police informed their WA counterparts of the alleged threat and the 16-year-old boy was arrested in Eaton near Bunbury on Tuesday afternoon.

He has been charged with one count of creating false apprehension to the existence of threats or danger.

The Eaton boy was granted bail and will appear in the Bunbury Children’s Court on April 4.

Prime Minister Anthony Albanese and NSW Premier Chris Minns have both condemned the alleged threat.

In a statement, the Australia Islamic House said they were "profoundly concerned" by the threat.

"The mosque's leadership is fully co-operating with the police to ensure the safety and security of its community members," Australian Islamic House president Mazhar Hadid OAM said.

"Our community deserves to feel safe and protected, just like any other citizen of this country.

"We call on the authorities to treat this matter with the highest urgency and to ensure that all places of worship are safeguarded against such acts of hatred and violence. We also urge the public to remain vigilant and to stand united against Islamophobia and all forms of bigotry."
