Police in Calgary are looking for the public’s help as they investigate an assault at an LRT station earlier this year.

On the evening of Jan. 30 a man who was preventing three women from boarding the C-Train at the downtown Sixth Street station was confronted by another man who stepped in to help the women.

That led to an altercation during which it’s believed the suspect tried to throw the other man onto the tracks, police said.

Both the suspect and the victim had left the scene by the time police arrived.

Investigators want to speak to the victim and ask that he contact Cst. Ryan Johnson at the District 2 office of the Calgary Police Service at 403-567-6271.

The victim is believed to be Asian, aged 25 to 40. He was wearing a black jacket, red and white baseball cap and had a backpack, police said.

The suspect is described as a Caucasian man in his 20s, six-foot-four, weighing 200 pounds with brown hair and a beard.

Anyone with information about the incident is asked to call police or Crime Stoppers
