Police have re-opened an investigation into the school that was allegedly involved in former principal and convicted rapist Malka Leifer fleeing Australia.
A probe into the conduct of others at the Adass Israel School in Elsternwick was launched in 2015 but suspended while the years-long criminal investigation into Malka Leifer was underway.
Victoria Police confirmed on Saturday that the Sexual Crimes Squad had resumed an investigation into possible offences linked to the ultra-orthodox Jewish girls' school.
"It would not be appropriate to comment further at this time," a police spokesperson said.
Malka Leifer was found guilty in April of 18 sexual offences relating to two former students between 2003 and 2007. She is yet to be sentenced.
Leifer flew to Israel in 2008 shortly after allegations against her were first raised.
The former principal was brought back to Australia in 2021 following a lengthy extradition process.
Former Victorian premier Ted Baillieu and former minister Philip Dalidakis, who have advocated for Leifer's victims, also confirmed the resumption of a police probe into the school board, sharing a letter they received from the office of the Chief Commissioner of Police Shane Patton.
"That investigation was suspended while the criminal proceedings against Ms Leifer were progressing," the letter reads.
"As the criminal proceedings against Ms Leifer have been finalised, Crime Command has re-commenced their investigation."
The letter from the office of Chief Commissioner Shane Patton was sent to Mr Baillieu and Mr Dalidakis in response to a letter from them, urging a thorough investigation into the conduct of anyone who may have perverted the course of justice.
Leifer fled to her native Israel in 2008 when allegations of inappropriate behaviour involving a student first surfaced.
The Supreme Court of Victoria found the wife of a school board member called a travel agent that night, and booked tickets for Leifer and four children to travel to Israel, via Hong Kong.
Leifer and the children left Melbourne Airport at 1:20am on March 6.
In a published judgement, Justice Jack Rush said those who organised the principal's departure were "determined to get Leifer out of the country within a matter of hours".
"The timing of the booking of the tickets and departure of Leifer and members of her family is extraordinary," he said.
Justice Rush said the school did not inform police of the allegations against Leifer before she left the country, and he said it was "likely" police were the ones who initiated contact with the school after The Age newspaper published a story on March 14.
