A man is scheduled to appear in court today, accused of carrying out a violent attack on a residence in north-west Sydney involving firearms and grenades.

On Thursday, November 27, two individuals reportedly tried to break into a home on Loura Street in Tallawong, armed with a sledgehammer.

According to allegations, one of these men attempted to shoot at the residence. When the weapon malfunctioned, he resorted to throwing a stun grenade into the house.

The duo then allegedly returned to their vehicle to retrieve another gun, firing two shots at the property.

Fortunately, the two people inside the home were not harmed during the incident.

The alleged attackers drove off in a Mazda CX5, before crashing it on Ashburton Crescent and running away.

They were tracked by the police dog squad to First Ponds Creek, where officers found the men’s clothing, including a balaclava, hooded jumper, pants and gloves.

During a search of the vehicle, police seized a live grenade, two firearms – including a loaded one – a magazine, a mobile phone and other items including bleach and clothing.

Police bomb disposal experts and Australian Defence Force personnel were called to safely remove the grenade.

Following inquiries to identify and find the men, about 10.15am yesterday, detectives arrested a 19-year-old man in Austral.

He was later charged with firearms, burglary and driving offences.

He was refused bail and is due to appear in court today.

Inquiries are continuing.
