A Mills man was arrested early Sunday after he allegedly tackled a Casper police officer.

William Steger, 35, was booked into the Natrona County Detention Center on a recommended charge of assaulting a police officer.

According to an affidavit of probable cause, Casper police were called to a residence in the 300 block of North Iowa at roughly 3:30 a.m. for a report of a large house party. When police arrived, it became apparent that there were roughly 30 to 40 people in and around the home.

Officers noted that most of the people at the party appeared intoxicated.

As officers attempted to clear the party, a man, identified as Steger, ran through police before tackling a female officer. Police immediately pulled Steger off the officer, according to the affidavit.

The officer hit her head on the ground when Steger allegedly tackled her.

A patrol sergeant on scene called an ambulance for the officer who was allegedly assaulted. Emergency services personnel determined that the officer did not need further treatment.

Steger is expected to make an initial court appearance Monday afternoon.
