Alberta RCMP officer acquitted of punching teen but guilty of separate assault

LEDUC, Alta. — An Alberta RCMP officer has been found guilty of one count of assault and acquitted of a second.

On Monday, a judge in Leduc, Alta., found Const. Eric Pomerleau not guilty of guilty of assault when he pepper-sprayed a teen who was in custody, then forced him to the ground and punched him in August 2012 in Red Deer.

Last week, an Edmonton judge ruled that Pomerleau was guilty of assault for using excessive force when he arrested a man suspected of impaired driving and brought him in for processing in Red Deer in December 2012.

Surveillance footage showed Pomerleau having an argument with the man after he refused to sign some documents.

The man was eventually taken to the ground and punched three or four times.

Pomerleau, who turns 31 this month, will be sentenced in Red Deer court on July 19.
