CONTROVERSIAL Chief Constable Richard Brunstrom is to face an inquiry over his use of the North Wales Police website to label people "idiots".
The issue will be discussed behind closed doors by the police authority's professional standards committee next week.
Authority member Darren Millar, a Conservative candidate at next year's Assembly elections, said there had been complaints from members of the public about the Brunstrom blog, which the Chief Constable updates just about every day.
Recent entries have criticised opponents of a needle exchange scheme as "nimbys" and called a driver a "dangerous idiot" after she broke the speed limit going to a speed awareness course.
Mr Millar, who is taking on Culture Minister Alun Pugh in the Clwyd West seat next year, said, "The use of blogs by senior police officers in North Wales is clearly causing considerable offence to some residents who have expressed serious concern to me about the way in which, the chief constable in particular, is using them to court controversy and media attention.
"While I accept that blogs can be a useful tool in communicating with the public, I am certain that calling people nimbys and idiots does nothing to improve the image of our senior officers and certainly does not give the air of professionalism that people should rightly expect from the police."
He added, "The type of language which sometimes appears in these blogs is usually reserved for either the playground, or the memoirs and diaries of senior civil servants long after they have departed from office."
Mr Brunstrom is no stranger to controversy. Having made his name with a crackdown on speeding and his liberal views of drugs, his blog has prompted further howls of anguish from critics.
Since it was set up this year he has called TV news "an insult to our intelligence" - and repeated his claim the police were once seen as an "army of occupation" in North Wales.
Before that he was rarely out of the headlines, having dispatched officers to Downing Street after allegations that Tony Blair swore about the Welsh back in 1999.
The offending post which prompted the complaint to the Police Authority was written two weeks ago. The chief constable wrote, "Mrs A was caught breaking the 30mph speed limit on the A547 at Abergele on 10 May 2006. She was offered and accepted a speed awareness course.
"Almost impossible to believe, Mrs A was done for speeding on the A548 at Prestatyn, on her way to the course. At one level this is funny - it certainly made me smile - but at another it most certainly isn't. It's dangerous idiots like Mrs A who are still recklessly endangering the lives of others."
