Senior man dies in August after attack at CTrain station over 'minor misunderstanding', police say

An 81-year-old Calgary man died from his injuries after an attack on the Sunnyside CTrain platform in August.

Tiamquan Yang was struck and fell onto a concrete platform in the early morning hours of August 15, Calgary police said.

He died on Oct. 22, the Calgary Police Service said in a statement Monday.

“An altercation over a minor misunderstanding led to Mr. Yang's assault and ultimately his senseless death. Our condolences go out to Mr. Yang's family and friends during this difficult time,” said CPS Homicide Staff Sgt. Martin Schiavetta in a press release.

Police arrested Basil Sweezy, 36, of Calgary, on Aug. 15 and charged him with aggravated assault.

Police said the attack is now being treated as a homicide.

Police said they would consult with the Crown prosecutor, but expect the charges to rise to manslaughter at Sweezy's next court appearance.
