Khoder Zahab, 42, was arrested Thursday after allegedly attacking and killing his father, Toufic Zahab, 69, with a brick and a knife inside his home, the Sydney Morning Herald reported. The suspect was charged with murder, common assault and assaulting police.
The attack allegedly happened after Khoder Zahab got into a fight with his mother; Toufic Zahab stepped in and his son hit him with a brick several times. The son then allegedly decapitated his father.
"The scene is quite disturbing," Detective Chief Inspector Glen Fitzgerald said. "It's been a difficult morning for both the family and police."
Fitzgerald said there were a number of other family members in the home at the time of the attack, the Australian Broadcasting Corp. reported.
"That's all still subject to investigation. Still very early, and there's a lot of statements currently underway," he said. "We've got a lot of family here. They were present at the home and the neighboring place -- it was a duplex owned by the entire family."
