The SIU says there are no reasonable grounds to suggest the officer committed a crime.
A Niagara Regional Police officer will not be charged after a man was injured during an arrest.
On June 27th, police were called to a restaurant on Lake Street in St. Catharines.
Investigators say a man was hitting other customers.
An officer told the man to leave the premises, but the man pulled away and continued to yell.
The officer searched the man and found what he believed to be a pocketknife.
To stop the man from accessing the knife, the officer forced the man to the ground by tripping him over his left leg.
The man was placed in the cruiser and was taken home after being released from custody.
About ten minutes later, the same officers were sent to a convenience store near the man's home,
Staff told police that the man entered the business with apparent injuries.
Upon arrival, police discovered the man was more injured than he appeared to be when he was released from custody.
The man was taken to hospital with a fractured left wrist.
It was unclear whether the injury occurred in the police takedown or in an altercation between the man and a restaurant patron before police arrived.
SIU Director Joseph Martino says there is no evidence to suggest the officer broke any laws.
