The man acquitted of the Russell Street bombing has refused to leave his cell to face court after being charged with the cold case kidnapping and rapes of two young women in the 1980s.

Peter Komiazyk and his co-accused, Russell Street bomber Craig Minogue, are facing 38 charges including abduction and rape over two incidents in 1985 and 1986.

The case of 61-year-old Komiazyk, who was charged over the bombing but later acquitted, was heard in the Melbourne Magistrates Court for a filing hearing today.

The court heard prosecutors have seized computers and USB from Komiazyk but need to conduct further analysis.

Minogue, 56, is currently in corrections custody and prosecutors have also made an application to obtain new DNA for testing.

The court heard Minogue has refused to provide his DNA.

The new charges relate to two incidents in 1985 and 1986.

In 1985, an 18-year-old schoolgirl was kidnapped from a South Yarra street.

She told police she was dragged into a car, blindfolded, driven to an unknown location and raped by multiple men over a number of hours, before being dumped in Richmond.

On March 26, 1986, a 19-year-old woman was also snatched off the street in Nunawading.

She too was sexually assaulted and then thrown out of a car in Ringwood.

The next day, she was inside the Russell Street police complex making a report about her gang rape when a bomb exploded.

Constable Angela Taylor was crossing the road nearby and died from her injuries three weeks after the blast.

Police say the 19-year-old sexual assault victim was shaken by the explosion, but confirmed she was not one of the 22 people injured in the attack.

Police allege the DNA of Komiazyk and Minogue was found on the alleged victims.

They also allege the DNA of Stanley Taylor, the other Russell Street bomber who has since died in prison, was also found on the second alleged victim.

Police matched the DNA to their criminal database in 2017, and immediately put Komiazyk under surveillance.

The father-of-two was arrested by officers from the Special Operations Group outside his psychologist’s office in Kalorama yesterday morning.

When Komiazyk appeared before a magistrate just before 7.30pm yesterday, he had a huge cut across one side of his face.

His lawyer claimed Komiazyk needs urgent medical attention.

Komiazyk also made an application for bail on grounds of his ill health and the fact he is the sole carer of one of his sons, a 13-year-old boy.

Police opposed bail, saying Komiazyk remains a risk to the community.

The magistrate refused the bail application, saying the crimes alleged were too serious.

Komiazyk's case will return to court on September 13.
