The son of WA's Police Commissioner will be released into home detention following a successful bail application in Fremantle Magistrate's Court today.
Russell O'Callaghan is accused of repeatedly assaulting and threatening to kill a woman while holding her captive in her south eastern suburbs home earlier this month.
He has spent the past week in Casuarina Prison while a home detention report was compiled.
The duty lawyer representing Mr O'Callaghan said her client was keen to address issues of substance abuse and tendered a letter from the Palmerston drug rehabilitation centre.
She said the 33-year-old would reside in home detention until he could be admitted to a rehabilitation facility.
Magistrate Steven Malley dismissed comments from the police prosecutor that Mr O'Callaghan was capable of "extreme violence" but did recognise the serious nature of his ongoing drug use.
Bail was set at $2000 and conditions included 24 hour home detention, urine testing and for Mr O'Callaghan not to use any drugs.
When asked if he understood the conditions placed upon him, Mr O'Callaghan said he did.
"I take the warning seriously," he said.
He will next appear in court on September 9.
