A man critically injured in a violent assault outside his Owen Sound, Ont. restaurant last week has died, police say.

In an update on Saturday, Owen Sound police said 44-year-old Sharifur Rahman died from the injuries he sustained from the Aug. 17 attack.

According to police, Rahman asked three men to settle their bill as he was about to close the restaurant. However, the men allegedly sparked a “dispute.”

At some point, police said the men assaulted Rahman and his nephew on the sidewalk outside the restaurant.

Rahman sustained serious injuries and was transported to London Health Sciences Hospital in critical condition. His nephew suffered minor injuries.

Police said Rahman died on Aug. 24.

Meanwhile, police continue to look for the male suspects. Security images of two of them were released earlier this week as police appealed to the public for help identifying them.
