Ontario's police watchdog says a Brantford police officer will not be charged in connection to a crash that left a cyclist with a broken tibia.

In a Thursday news release, the Special Investigations Unit said they found no grounds to believe the officer committed a criminal offence.

The crash happened on Oct. 6 just before 1 p.m. in the area of Colborne and Echo Streets.

The officer reportedly hit a 47-year-old cyclist when they were making a right hand turn, and stayed with him until paramedics arrived.

The SIU says the officer was largely responsible for the collision, but that "it was a momentary lapse of attention that does not give rise to criminal liability."
