He referred to it as his ''party trick'' - exposing his genital piercing, or opening a beer bottle with a bottle opener attached to it.

And police officer Sergeant Andrew Lawrance is certain no one was offended when he performed the trick to a small group of fellow officers and their wives at a Christmas party at Tommy's Chinese Restaurant in Yamba, egging him on.

One woman, he told the Industrial Relations Commission yesterday, had asked to see the piercing after he talked about it.

One man, however, took offence: his ultimate boss, Police Commissioner Andrew Scipione, who wants Mr Lawrance gone from the force, saying he has lost confidence in him. He argued the offence was made worse by the fact that Mr Lawrance was one of the most senior officers at the party in December 2008.

Mr Lawrance said there were no other patrons left at the Yamba restaurant when he went to the toilet to attach the bottle opener to the piercing, before exposing it two or three times to about six other people including his wife.
