Convicted murderer Judy Moran spat in the direction of other prisoners and ran over an inmate's foot with her electric wheelchair in a jailhouse row, a court has heard.

The gangland widow who was convicted in March of orchestrating her brother-in-law Des "Tuppence" Moran's 2009 execution was being kept at bay from three other prisoners at the Dame Phyllis Frost women's jail following security concerns, the Victorian Supreme Court heard on Monday.

The court heard Moran, 66, was living in cottage accommodation at the prison but was moved to a management unit earlier this month as a result of a security incident sparked by a newspaper article stating Moran "expected to be waited on hand and foot".

Moran had complained the article breached her privacy and accused other prisoners of sharing information about her, leading other inmates to threaten her.

She had also spat in the direction of other prisoners and ran over one's foot using her electric wheelchair, the court was told.

After the incident, Moran was moved to a management unit known as "the slot" for 19 hours for her safety before returning to the mainstream jail population.

The evidence came during Moran's further pre-sentence hearing regarding her health concerns, which her defence claims will make her jail time more onerous.

Justice Lex Lasry will sentence Moran at a date to be fixed.

former prison mate of slain gangland killer Carl Williams could be quizzed over bribes he allegedly made to a former policeman.

Tommy Ivanovic is alleged to have made an unsworn statement to police about the bribes. His statement was corroborated by one made by another man who is now dead, a police ethical standards investigator told the Melbourne Magistrates Court yesterday.

Detective Sergeant Jason Lebusque of the police Ethical Standards Department applied to the court to question Ivanovic in custody over the matter.

Magistrate Jelena Popovic adjourned the application until next Monday.

Last month, a magistrate gave police permission to interview Ivanovic over an attempted murder 12 years ago.

Ivanovic is serving 20 years’ jail, with a 15-year minimum, for murder over a road rage incident in 2002.

Magistrate Gregory McNamara granted police six hours to quiz Ivanovic over the attempted murder of Westmeadows man Leigh Pascu, then 32, in 1999.

Ivanovic shared a high-security unit at Barwon Prison with Williams and Matthew Johnson.

Johnson will stand trial in September, accused of bludgeoning Williams to death with a bike shaft on April 19 last year.
