A McHenry man is facing home invasion and aggravated battery charges after he allegedly broke into his ex-girlfriend’s home and attacked a man on Friday.

The McHenry Police Department responded at 10:30 p.m. on Friday to a 911 call in the 1700 block of Highview Drive for a report of a disturbance at a home.

The 911 caller told dispatchers that James K. Kaiser, 46, of the 1000 block of North River Road in McHenry, had entered the home and hit a man who was inside. When police arrived they found Kaiser outside the house. He was taken into custody without incident.

Authorities said that an investigation revealed that a woman who Kaiser was previously in a relationship with lived at the house. Three adults were inside the home when Kaiser allegedly broke in.

The man who was assaulted was injured, but refused medical treatment, police said.
