The principal of a Jewish girls' school charged with dozens of child sex offences has been accused of molesting other female prisoners by an Israeli politician.

Malka Leifer, 54, is wanted in Australia on 74 sexual assault charges, including rape, involving girls at the Adass Israel, an ultra-orthodox school in Melbourne.

Leifer on Monday was accused of molesting young women in the Tirza prison, south-east of Tel Aviv, by Jerusalem Deputy Mayor Fleur Hassan-Nahoum.

'There is even allegations she's abusing girls in the jail that she's in at the moment,' Hassan-Nahoum said outside Jerusalem District Court, The Australian reported.

'This woman abused before she went to Australia. This woman abused after she ran away from Australia,' the mayor said.

'Justice has to be brought to the victims of this case. Not just the victims in Australia, but the tens of victims in Israel, Australia and many other places.'

Leifer fled Australia in 2008 after accusations against her surfaced and the country has since been pressing Israel to extradite her back.

Israeli authorities did not act on Australia's extradition request until 2014.

An Israeli court in 2016 ruled Leifer was mentally unfit to face extradition and trial. She has denied accusations made against her in court.

She was arrested again in 2018 after police became doubtful of her health claims and remains in an Israeli prison.

Leifer on Monday was hit with fresh accusations after judge Chana Lomp ordered psychiatrists to investigate her claims she was unfit to face court due to her mental health.

A fresh panel of state psychiatrists will replace the ones who have been assessing Leifer every six months.

Israel's Office of the State Attorney have claimed she has faked her mental health problems to avoid court appearances.

Leifer's lawyers claim she has been struggling with anxiety and panic attacks due to the pressures to face court.

But undercover CCTV caught Leifer shopping and talking to friends in public, which contradicted her claim she was too unwell to leave home.

Judge Lomp said the conflicting arguments about her mental health meant she needed a new group of psychiatrists to assess her.
