**Updated** Petit de Grat senior charged in historical sexual assault investigation

**Updated at 5 p.m.**

A 90-year-old Nova Scotia man has been charged with multiple historical sexual offences against children spanning two decades.

Delmore Boudreau of Petit-de-Grat has been charged with 12 sexual offences that occurred on the southeastern island of Isle Madame between 1966 and 1986.

Police say nine victims, aged four to 12 at the time of the abuse, have been identified and they expect more victims could come forward.

Richmond District RCMP in Arichat launched an extensive eight-month investigation into allegations of historical sexual assaults after a victim came forward to police.

It's unclear what Boudreau's role was in the small coastal community.

Police would not say what his position may have been in order to protect the identity of the victims.

"What we're trying to do here is protect the identity of the victims," Cpl. Jennifer Clarke said Wednesday. "It's a very small community and a huge issue for that community and those are serious offences."

Boudreau is expected to be in court in Port Hawkesbury on May 28.

"It's a very courageous thing for a victim to come forward," Clarke said. "The purpose of the release for us is that there may be more victims out there."
