WHITBY, Ont. -- A 20-year-old man faces charges after police say an officer was choked at a bar east of Toronto.

Durham regional police say officers responded to a call of male patrons causing a disturbance at a Whitby bar around 2:25 a.m. Saturday.

They allege one of the men jumped an officer from behind and started to choke him while police were in the process of arresting a second man who they say refused to leave.

The officer was taken to hospital for a checkup but was not injured in the incident.

Cameron Peck of Port Hope is charged with assaulting a peace officer and causing a disturbance.

A second man was arrested but released unconditionally.
