SAVANNA, Ill. — A Savanna man has been charged with concealing or aiding a fugitive and aggravated battery of a police officer after an altercation Saturday night.

Michael J. Denson, 21, also was charged with resisting a peace officer after police were called to a Savanna residence shortly before 9:30 p.m. Saturday, according to a press release from the Savanna Police Department.

According to the release, an officer observed a wanted man, Nathan T. Green, 40, as he entered a residence. The release states that after confirming the warrant was still valid, officers attempted to make contact with him, but he continued into the home.

Denson, who lived at the same residence, is accused of making several attempts to barricade the door and to block officers from entering the residence. Police also say he was threatening officers with a dog that was inside the home. The release says that as officers entered the structure, the dog was allowed to charge at them and that in order to prevent being attacked, an officer shot the dog. The dog sustained a non-life threatening injury, police said.

The release says Denson then attacked the officer and injured him. Another officer deployed a Taser to stop the attack and take Denson into custody. The officer was removed from the scene and taken by Savanna ambulance personnel to the MercyOne Clinton emergency room. Green then was arrested on the warrant.

According to police, additional charges are pending against Green, Denson and another subject, who was not identified in the press release but who police say was also at the residence.

The officer was treated at the hospital and later released.
