Twelve firearms, a motorcycle and a Toyota Hilux have allegedly been stolen from a McGraths Hill home while a family of four was asleep inside.
Police will allege two men broke into the Havelock Street home between midnight and 5am on Tuesday, September 17, and stole the firearms and two vehicles, as well as power tools.
"A family of four - including a four-year-old boy and a six-year-old girl - were inside asleep at the time," a police statement said.
"Detectives from Hawkesbury Police Area Command and the State Crime Command's Robbery and Serious Crime Squad commenced an investigation under Strike Force Ilet.
"Following extensive inquiries, strike force investigators, with assistance from operatives from the Tactical Operations Unit, executed two search warrants at homes on Bolderwood Road, Blackett, and Pank Parade, Blacktown, about 4pm yesterday (September 18)."
Three rifles and three shotguns were seized from the Blackett home, police stated.
A 29-year-old man was arrested at the Blackett home and taken to Mt Druitt Police Station. He was charged with aggravated break and enter and committing a serious indictable offence, supplying a firearm with no firearms dealer or police witness present, possessing more than three unregistered firearms, and receiving or disposing of stolen property.
Police will allege in court that the man attempted to sell the stolen items following the break-in.
He was refused bail to appear at Mt Druitt Local Court today (September 19).
