A photograph obtained by Fairfax Media shows Jennifer West, an area manager at the Alexander Maconochie Centre, sitting at a cafe with former ACT Rebels president Martin Stefancic.

The directorate has investigated and cleared Ms West over her alleged links to outlaw bikies, and a spokesman said "no further action was required".

In the photo, Ms West sits across from Mr Stefancic, with a cup of coffee and a half-eaten plate of scrambled eggs in front of her.

The photo was reportedly taken in August 2016.

When shown the picture, the directorate's spokesman said it generally did not concern itself with "personal relationships", unless there was a potential conflict of interest.

He also said Mr Stefancic had never been a "client" of ACT Corrective Services, presumably a reference to the former bikie boss never being an inmate in Canberra's jail.

"Employees are required to take all reasonable steps to avoid a conflict of interest and [to] declare or manage a conflict of interest that cannot reasonably be avoided," a directorate spokesman said.

Late last year, Fairfax applied under freedom of information law for any documents related to prison staff's alleged involvement in criminal activity.

The documents released revealed a letter was sent to the ACT government in February 2017, detailing several allegations regarding a "senior correctional officer".

The anonymous letter referred to two news articles, which had named then Rebels president Martin Stefancic and prison manager Jennifer West.

This letter sparked an internal investigation, which was completed in December 2017.

Details of the investigation were almost entirely censored before being released, although the directorate provided a summary of the actions it had taken.

"This information has been referred to ACT Policing," the investigation summary read. "ACT Policing have responded to indicate that there is no specific indication that there has been any criminal conduct."

In response to questions about the investigation into Ms West, the Justice Directorate said the investigation had determined no further action was needed.

"The substance of the allegation had been investigated appropriately," a spokesman said. "No further action was required."

Ms West referred Fairfax's questions to the Justice Directorate.

Several criminals with links to the Rebels gang have been locked up inside the Alexander Maconochie Centre in recent years, including Fakatounaulupe Ngata, who was jailed for aggravated robbery, and Alex Bourne, who was jailed for grievous bodily harm.

Bourne has since patched over to the Comanchero motorcycle gang, while it is understood Ngata was deported.

In 2016, prison officers confiscated a painting with Rebels gang insignia on it after an inmate was found to be hiding it in his cell.

The directorate said it kept a constant eye on potential conflicts of interest among prison staff.

"Conflicts of interest – perceived or actual – are continually assessed, including consideration of the roles and duties of employees and appropriate action taken to manage the conflict," a spokesman said.

"Any conflict of interest – perceived or actual – which involves criminality will always be referred to ACT Policing."

Mr Stefancic made headlines in 2005 while he was the president of the Rebels' ACT chapter.

At the time, the Rebels threatened to violently remove cloth patches worn by members of a visiting social motorcycle club.

When asked by a reporter whether Rebels had threatened Ulysses members with violence, Mr Stefancic said: "Whatever – that's what they say.

"Whatever it takes mate. If you want to play the game, you want to be in shape to play it, don't you."
