The mayor of Port Coquitlam, B.C., yelled profanities and uttered threats on the night he assaulted his ex-girlfriend and her new partner, according to a 911 tape played at his sentencing hearing on Friday.

Scott Young, who pleaded guilty in May to two charges of assault and one charge of breaching the conditions of an undertaking, was given a 12-month conditional sentence to be served at home, with a curfew from 8 p.m. to 6 a.m. except to attend council meetings.

He has also been placed on 18 months of probation, was ordered to perform 60 hours of community service, must stay away from former girlfriend Colleen Preston and her partner, Glen Shaw, and abstain from alcohol and drugs.

Crown lawyer Emmet Duncan said the sentence was "within the range proposed by the provincial Crown."

Before handing down the sentence, provincial court Judge Kimberly Arthur-Leung released audio of the 911 call Preston made on April 4, 2007, when Young ignored previous court orders to stay away from her and broke into her home. He had been arrested for allegedly harassing Preston two months before but no charges were laid.

During the call, Young swung from yelling profanities at Preston to shouting how much he had cared for her.

Young is heard on the recording saying, "I believed in you. I loved you," "F--- you!" and "You f--ing b----!" as Preston is reporting the incident to an emergency dispatcher on the telephone.

The judge cited a psychiatrist's report describing Young as a "rejected stalker."

Young had faced seven criminal charges, including assault, criminal harassment and breaking and entering, but the Crown stayed the proceedings on four charges.

"I recognized my errors. I apologized to those involved and to my community on numerous occasions," said Young, who has been mayor of Port Coquitlam since 2001. He had previously served as a city councillor and a school trustee.

Many residents have been calling for Young to step down since he pleaded guilty to assault charges in May. His council has asked him to leave three times.

He temporarily stepped aside but returned to the mayor's chair a month and a half after the April 2007 incident.
