A report by the Law Enforcement Conduct Commission (LECC) — a police oversight body — found the policeman, known as Officer 1, engaged in seven counts of "serious police misconduct" over a five-year period.

His unlawful activity also included spying on his girlfriend's ex-partner via unauthorised access to the Computerised Operational Policing System (COPS) database.

Misuse and breaches of personal information in the COPS database, which holds about 40 million records on people in Australia, was yesterday revealed in an ABC investigation.

The report probed Officer 1's "intimate relationship" with a local pub owner, referred to as "Ms A".

It described how Officer 1 breached the COPS database by running a search on Ms A's former partner.

The report said the ex-partner "was wholly unconnected" with Officer 1's duties and "the access was improper and unauthorised".

When asked to explain, Officer 1 said he "may have thought" about a matter that "occurred years ago and just had a read".

The report also found Officer 1 encouraged colleagues to forge his signature on official documents, including subpoenas.

On a wire-tap recording, a fellow officer joked about this practice and said "I forged your signature on a few".

Officer 1 explained to investigators the forgeries saved him time doing paperwork.

False documents used to fund Mercedes Benz

The report claimed Officer 1 made six applications for finance with false or misleading information, sometimes with the help of Ms A.

This included misrepresenting a $24,000 loan from Ms A as his own savings to secure a home loan from the ANZ Bank.

He also financed a Mercedes Benz, and obtained credit cards with false documents.

The report found four of the cases "constitute a criminal offence of fraud" and recommended his further prosecution.

While his lawyers denied "any dishonest deception", the report said Officer 1 was "putting forward a financial image of himself that did not reflect the complete picture".

It also described his elaborate scam to take money out of a superannuation account he had with his wife, and give his mistress, Ms A, $120,000.

In evidence, Officer 1 admitted forging Ms A's signature on a loan agreement, and accessing money held in her name.

The report said this amounted to serious police misconduct.

Officer 1 also carried out nine official inspections of his lover's pub after their relationship began in 2011.

The conflict of interest created by his relationship with Ms A, and his ongoing failure to perform his duties, were repeatedly highlighted in the report.

The report found Ms A was "involved in the lending of significant amounts of money" to Officer 1, ultimately providing $50,000 towards purchases including two cars and a block of land.

The report also detailed how Officer 1 failed to act on an incident reported to him by Ms A, involving a woman armed with a rifle and making threats at a farm.

The incident was not reported by Officer 1 and the report found he "failed in his duties by not doing so".

The LECC told the ABC it was "still gathering evidence in admissible form" for the DPP on the potential charges.
