A former federal counter-terrorism officer allegedly used stolen information on his ex-girlfriend and her new partner in an attempt to split the couple, a court has heard.
Roman Eiginson, 52, allegedly used some of the information to tell the woman’s family the man was a terrorist and violent.
Eiginson was arrested and charged with stalking in April.
He has pleaded not guilty to the charge.
The defendant was also charged with divulging prescribed information when he appeared in the ACT Magistrates Court on Friday.
No plea has been entered to that charge.
The court heard Eiginson, who now works in the Australia Federal Police’s treasury section, started a relationship with the complainant in June 2009.
But the affair soured after Eiginson married a woman from Russia and the pair split in March this year.
Eiginson, a former Soviet Union soldier and police officer, allegedly continued to harass his ex-girlfriend in an attempt to win her back.
A police informant told the court Eiginson had not been authorised to access the police database when he logged on and collected information about his ex-girlfriend and her new partner on three days in mid-April.
Police alleged he used the database to find the woman’s phone number and address and drove his car up and down slowly outside the couple’s home on a number of occasions.
Police also allege Eiginson discovered the registration for the man’s BMW, slashed the prestige car’s tyres, and then logged in to check the police report at work later that day.
Eiginson was allegedly found by police hiding behind a tree about 30 metres from the couple’s home on April 19.
He was told to leave the area but they allegedly discovered him sitting in his parked car nearby soon after.
The accused was arrested later that day.
During interactions with police he allegedly said: “Thank you for confirming she lives here.”
Prosecutor Diana Likeman opposed Eiginson’s bail application on the grounds he could offend or interfere with the investigation if released on bail.
The informant - an agent from the AFP’s professional standards division - said the defendant had twice made threats against the woman, including telling a friend in early April he would kill her before killing himself.
Upon entry to Canberra jail, he also allegedly told a nurse during a health check he would not harm himself until he could get "that b----".
The court heard that during a visit with his superintendent upon his arrest, the accused told his superior he would get the woman to drop the charges and outlined a plan to do so.
But defence lawyer Shane Gill said the basis for the bail opposition and allegations his client had access to guns had only been speculation.
Magistrate Robert Cook refused Eiginson bail, saying he posed a substantial threat to the complainant and could interfere with the investigation.
The matter will reappear later this month.
