Former NSW policeman Robert John Reid has been found guilty of misleading the Police Integrity Commission.

A former NSW policeman has been found guilty of misleading the Police Integrity Commission over an alleged drug-fuelled weekend with fellow officers on the Gold Coast.

Robert John Reid, 45, pleaded not guilty to three counts of giving false or misleading evidence at a hearing before the police watchdog in October 2011.

At the commission, Reid was quizzed about an alleged bender he and former and serving officers went on during a boys weekend in Queensland in 2010.

The former officer said he did not remember whether anyone else ate hash cookies or took ecstasy or cocaine.

He also denied supplying the illicit drugs for the Gold Coast jaunt, saying another of his “mates” had been responsible for the hash cookies.

But Magistrate Peter Barnett rejected the claims on Thursday, saying surveillance footage – which had been secretly installed by investigators at the Gold Coast apartment – clearly showed Reid bringing hash cookies into the room before proclaiming: “Help yourself guys, go nuts.”

At another point, Mr Barnett said Reid could be seen going into a corner “doing something with a packet” and saying to the room, “Do you want a pill?”

The court heard Reid had claimed he was so intoxicated he could not recall what the others were doing.

A friend, former policeman Joshua Smith, and Reid’s wife, Wendy, told the court how he became “obnoxious, belligerent, aggressive and loud” when drunk and that once a particular “switch had flicked” he would often forget what he had done the night before.

Mr Barnett said Reid would ask them, “What did I do last night and who do I need to apologise to?”

The magistrate did not dispute the truthfulness of Mr Smith and Mrs Reid’s evidence, but said he did not believe the 45-year-old had been so drunk that weekend that he forgot what happened.

Footage taken on one of the mornings after the evening drinking sessions shows Reid asking one of the other men, “How many of those f***ing pills did you ram down your throat?”

Reid will face sentencing in September.
