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.

Kaiser is being held on a $20,000 bond and is facing charges of home invasion/cause of injury (class X felony) and battery/cause of bodily harm (misdemeanor). He is next due in court on Wednesday.
