CANTON -

A 24-year-old man pleaded not guilty on assault charges after allegedly stabbing an officer in the face with a piece of wood from a broken door jamb.

Police say the 22-year-old officer sustained minor injuries when he was hit near his eye while trying to help the suspect's girlfriend during a domestic assault incident. The officer was responding to the domestic dispute call at around 4 a.m. at the College Park Estates mobile home community on Mott Road. He forced the door of the home open, breaking the door jamb, authorities say. Police say the suspect then picked up a small piece of wood from the broken jamb and stabbed the officer.

The defendant, 24-year-old Nicholas Gregory Schumann (pictured above) is charged with assault with intent to do great bodily harm (less than murder), assault with a dangerous weapon, assaulting, resisting and obstructing a police officer causing injury and aggravated domestic violence. He received a not-guilty plea on his record and was jailed awaiting a preliminary exam on Sept. 5.

If convicted, Schumann could face up to 10 years in prison.

Schumann's girlfriend was given treatment for her swollen eyes and face after the assault. The woman was more seriously hurt during an earlier assault.

A 2-year-old boy and 3-month-old girl were in the house at the time, but neither were injured.
