CALGARY -- Calgary police are looking for the public's help to identify two men believed to know something about an unprovoked attack on a 34-year-old man last week.

Officials say the victim was outside the Save-On-Foods store at Richmond Square, on 51 Street S.W., between 8:25 and 8:40 p.m. on Jan. 23 when he was seriously assaulted by another man.

Following the incident, the suspect fled northbound where he was joined by another man who was there at the time of the attack but did not participate.

The victim was taken to hospital where he received treatment for severe injuries to his face and head.

Police say they have not determined the motive for the incident.
