MARION — Police arrested a man and placed him under medical observation after he assaulted a woman in Osceola County while speaking only in grunts and pounding his chest.

According to a Michigan State Police press release, troopers were dispatched to a house in Middle Branch Township Wednesday for an assault in progress.

A trooper arrived on scene and located the suspect trying to pull the victim from her car and stab her with her keys.

It was learned from the victim she had been attacked by the suspect when she pulled into her driveway and exited her car. She told police the suspect approached her grunting loudly and beating his chest with his fist.

The victim fought off the suspect and ran into her house while he attempted to steal another vehicle.

He then returned with a gas can and poured it on the home and tried to light it on fire. The suspect then broke into the house through a window and entered the home and continued to chase her. She was able to escape and run back to her car. The suspect was pulling on her steering wheel while she tried to drive away, causing her to crash into a tree.

According to the report, the suspect was unable to speak anything but loud grunts and was glaring at anyone who would speak to him.

The suspect was resistant to the officer's directions and was transported to the Reed City Hospital for medical observations. He was then lodged in the Osceola County Jail.

The Osceola County Prosecutor's Office authorized charges for home invasion first degree, arson-preparation to burn, resisting and obstructing, unlawful driving away an automobile, and habitual offender-fourth felony offense.
