A SENIOR police officer who waged a campaign over the internet of sexual humiliation against his ex girlfriend has received a suspended sentence.

Detective Sergeant Darren James Clohesy was originally charged with stalking but pleaded guilty to the lesser charge of offensive behaviour.

He also admitted to twice breaching his bail conditions and to improperly accessing the police computer system.

The charges related to his failed relationship with Tania Milsom, a fellow police officer, which ended in early 2009.

Passing sentence in the Adelaide Magistrates Court today, Chief Magistrate Elizabeth Bolton said to describe Clohesy's behaviour as despicable would be an understatement.

"You provided the details to allow this nasty, hurtful and malicious scheme to take place," she told the 41-year-old.

Ms Bolton said that after Clohesy had been rejected by his girlfriend he helped another woman set up the profile on an adult internet dating site.
It provided Ms Milsom's phone number and address and encouraged men to contact her for sex.

A number of men contacted the site and went to the Ms Milsom's home, with at least one knocking on her bedroom window.

It was Clohesy who provided his former girlfriend's details for the site, something central to the plot, the magistrate said.

Without those details, nothing would have come of the other preparations.

Ms Bolton said the scheme had been designed to embarrass, frighten and degrade the woman who had rejected Clohesy.

The policeman, who was promoted to head up the Operation Mandrake anti-gang taskforce in 2009, was jailed for a total of 18 months with a non-parole period of nine months.

However, the sentence was suspended with the magistrate placing him on a two-year good behaviour bond and ordering him to perform 320 hours of community service work.

Clohesy was suspended on full pay following his arrest.

He was suspended without pay after he pleaded guilty two weeks ago.

His future with SA Police will be decided next week at a disciplinary hearing.

One of the options available to Police Commissioner Mal Hyde is sacking him.
