Toronto ? A Canadian man who sexually abused his 4-year-old daughter live on the Internet so another man could watch was sentenced Thursday to four years in prison.

The father, whose name was not released to protect the identity of his daughter, was arrested in October 2006, just hours after he used a Webcam to expose his daughter to another man – who was actually an undercover police officer – during a chat room conversation.

The father from St. Thomas, Ontario, pleaded guilty in October to seven criminal charges.

In sentencing him, Justice John McGarry called it a “gross case; a sickening case of breach of trust.”
