Canadian man stabbed to death at work. Police say a suspect has been arrested.

A 55-year-old man was stabbed to death at work by a 25-year-old suspect and now police say that attacker has been arrested.

Around 9 a.m. on Dec. 30, officers responded to a weapons call at Insight Optometry in downtown Halifax, Nova Scotia, the Halifax Police Department said.

According to authorities, 25-year-old Cymon Felix Cormier entered the business and stabbed a staff member, who was later identified as 55-year-old Tony Nader.

Cormier ran away before police arrived, but officials said he was arrested in the area a short time later.

Police said a customer of the business, a 66-year-old man, tried to intervene and was also injured. He was taken to the hospital with non-life-threatening injuries.

Nader was taken to the hospital with life-threatening injuries, where he died, police said.

Will Hansen, who knew Nader from the guitar-trading community, told CTV News that Nader was “somebody that is beloved by so many people across the Nova Scotia area. You knew Tony, whether you knew him well or not, you felt like you had a friend for life.”

According to investigators, they believe this was not a random incident.

Cormier was arrested and charged with first-degree murder, assault causing bodily harm, assault with a weapon and possession of a weapon dangerous to the public, authorities said.

He is set to appear in court again on Jan. 28, police said.
