KINGSTON, Ont. -- Police say a 20-year-old Kingston, Ont., man is facing charges after allegedly pulling a knife on an officer during a road rage incident.

They say a plainclothes officer with the Kingston street crimes unit was driving an unmarked car when the incident occurred on Tuesday night.

It's alleged the accused, who was driving a motorcycle side-by-side with two other bikes, gestured at the officer with his middle finger and the officer noticed the riders were wearing patches aligning themselves with a motorcycle club.

When the officer turned around to get licence plate numbers, the bikes pulled over and the officer confirmed two of the riders were wearing Outlaws MC vests while the third had Outlaws MC stickers on his motorcycle.

Investigators allege the accused got off his motorcycle, approached the officer in an aggressive manner, pulled out a large hunting-style knife and made a stabbing motion as he began yelling.

The officer identified himself and arrested the man, who faces charges that include assault with a weapon, possession of dangerous weapon, carrying a concealed weapon, possession of a prohibited weapon and intimidation by threats of violence.
