A 48-year-old sergeant, attached to a local area command within the northern region, will face court next year charged with misconduct and firearm offences.
He was served a Future Court Attendance Notice yesterday following an investigation by the Professional Standards Command.
Police media have declined to name the officer or to mention which local area command he is from but have said he is due to appear at Tweed Heads Local Court on 14 January 2013.
The sergeant will face charges of misconduct in public office; aid and abet possess unauthorised pistol; and allow unauthorised person to possess pistol.
Police will allege the incident occurred while the officer was on duty in 2011.
