Two men arrested last month for allegedly throwing rocks at numerous moving vehicles in 2024 – seriously injuring two people – now face additional charges stemming from two other incidents.

The two 18-year-old men, of Markham and Richmond Hill, were originally charged on July 2 with aggravated assault, mischief damage to property and mischief endangering life for incidents that occurred between Sept 20. and Nov. 30, 2024.

Ontario Provincial Police say the accused, who were underage at the time of the incidents and can’t be named under the Youth Criminal Justice Act, have now each been charged with two counts of assault with a weapon and two counts of mischief endangering life relating to two other incidents.
