A Toronto police officer has pleaded guilty to one count of threatening bodily harm after being caught on video intimidating two people in custody with a Taser.

Video released Monday during Const. Christopher Hominuk's trial shows the officer using his Taser to try to exact information from the men.

The video was captured on May 24 while police were investigating a theft call in Etobicoke. It shows an officer holding a Taser to a man's neck while the man lies in handcuffs across the back seat of a police cruiser. In the same video, the officer can be seen threatening a second man's genitals with the Taser, saying he will be shocked if he fails to co-operate.

On Monday, a spokesperson for Chief Bill Blair described the officer's behaviour as "disgraceful."

The officer did not discharge his Taser on either prisoner, the court heard.

Hominuk, who is 37 years old and has 13 years of police service behind him, was charged and suspended from duty with pay in June 2010. He was most recently posted with 22 Division in the city's west end.

He is set to be sentenced at the College Park courthouse on June 14, 2011.
