Convicted Maple Leaf Gardens sex offender Gordon Stuckless is facing 19 new charges in connection with the sexual assault of three boys more than 30 years ago, police announced Wednesday.

The charges stem from incidents that allegedly occurred between 1978 and 1984.

Stuckless is currently serving a six-and-a-half year prison sentence after pleading guilty to 100 charges related to the sexual abuse of 18 victims.

At a sentencing hearing in April, Stuckless apologized to his victims, noting that he was ashamed of his actions.

"I know that I have caused a lot of harm, pain and shame to all of you," he said at the time.

Stuckless previously pleaded guilty in 1997 to a number of charges that were filed in connection with the sexual assault of 24 boys while he worked as an equipment manager at Toronto's Maple Leaf Gardens between 1969 and 1988. He ended up serving four years in prison on those charges and was released in 2001.

The new charges include four counts of indecent assault male, four counts of buggery, six counts of gross indecency, three counts of sexual assault and two counts of threatening death.

Stuckless is scheduled to appear in court at Old City Hall on Thursday.
