TWO senior NSW police suspended on full pay are still under an internal police investigation more than a year after testing positive for cocaine.
Detective Inspector Shane Diehm, who was crime manager at Tweed-Byron station, and Inspector Matthew Dennis, who was at Hunter Valley police station, were both stood down in August last year.
Australian Federal Police sky marshal Darren Kolosque resigned after positive drug tests.
The three were at a party at a Paddington pub on August 5 last year for the retirement of former detective superintendent John Alt, who is now under a separate Police Integrity Commission investigation.
But the police professional standards command, which looks into NSW police misconduct, is still investigating the two senior police more than a year after they failed the tests.
A police spokesman could not say why the investigation was taking so long. "Two officers from the northern region remain suspended on pay pending the finalisation of the matter," he said.
Mr Diehm, who recently coached a Mullumbimby Giants rugby league club, declined to comment when contacted through family by The Sun-Herald.
There was a similar police response to questions about the internal investigation into Northern Beaches Constable Ryan Godfrey.
In June, The Sun-Herald revealed Constable Godfrey inappropriately used a Taser on Michael Lindsay, who had been arrested on a bus when returning home from a golf day celebrating his 26th birthday in May last year.
Constable Godfrey lied in court about the reason for arrest and subsequent Taser use. Two other officers along with four transit officers all corroborated Constable Godfrey's version of events.
Police are still investigating the matter, six months after the magistrate, Lee Gilmour, said: "Clearly, unfortunately, this officer [Godfrey] has lied."
"A professional standards command investigation is continuing. It is inappropriate to comment further," the police spokesman said.
The Greens MP David Shoebridge said Britain had a much better complaint model through their Independent Police Complaints Commission, which reports directly to Parliament.
"These series of cases in NSW show public confidence would be improved if there was a genuine independent and adequately funded police oversight body," he said.
