Hamilton police say the investigation into a shooting where a senior allegedly shot a man breaking in to his home has revealed that the break and enter wasn't random.

Investigators say they were called about reports of a home invasion and shooting at a residence on Avondale Street near Barton Street East and Gage Avenue North just before 10:30 p.m. on Thursday.

Detectives announced on Monday that the 65-year-old homeowner and the shooting victim, a 24-year-old Hamilton man, both know each other.

Police say that the 24-year-old went to the Avondale Street home and an altercation broke out.

"The 24-year-old male attempted to force his way into the home at which time he was shot by the home owner and fled the scene," the news release reads.

It notes that "The evidence collected from the scene and witnesses support the firearm charges as well as the aggravated assault charge laid against the home owner."

The 24-year-old is also facing charges of breaking and entering.
