MINNEAPOLIS (WCCO) – Minneapolis Police need help in finding the person who attacked a 65-year-old man and permanently injured him.

The incident happened on June 25, 2012 on the sidewalk on Lake Street West near Grand Avenue South in Uptown.

Police say the victim stopped three men who were riding bikes on the sidewalk, because they almost hit him.

Officers say his conversation with one of the men got heated, when all of the sudden he was attacked. Police say the suspect punched the victim in the throat, broke his larynx and damaged one of his vocal cords.

According to Sgt. Mark Osland, one more punch could have been killed the victim.

On Thursday, police released surveillance video and photos from the scene because they haven’t been able to track the suspect down. They’re hoping someone may recognize him.

Police believe the man is in his mid- to late-20s, between 5-feet-8-inches and 6-feet-tall, with a medium build.
