The Sûreté du Québec has charged a Cornwall police officer with sexual touching, internet child luring and two counts of prostitution of a minor.

Constable Pascal Rossignol appeared in Quebec provincial court in Valleyfield, Que., on Friday, Cornwall police said in a statement.

The Quebec provincial police agency said the charges come after a two-year investigation.

On Oct. 13, 2010, the allegation was made to Cornwall police, who referred the matter to Ontario's Special Investigations Unit, which investigates allegations of sexual assault involving police officers.

But the SIU determined the alleged events happened in Quebec and handed the case over to the SQ.

Rossignol has been with the Cornwall Community Police Service since May 2007. He was relieved of his duties and remains under suspension with pay, Cornwall police said.

Anyone with additional information about this investigation is asked to contact Staff Sgt. Garry Derochie at (613) 933-5000 ext. 2411.
