CHADRON, Neb. - Authorities arrested a suspect accused firing shots from a semi-automatic rifle south of Chadron State College and leading law enforcement on a four-hour manhunt Friday night. 

The Chadron Police Department responded to the college in Dawes County at approximately 6 p.m. Friday night. Authorities said they were looking for an armed gunman with dark clothing in the "C-Hill" area south of the college. 

Authorities were tracking the suspect through trees and hills near the 2600 block of Maple Street at 10 p.m. The manhunt advanced as far east as the Ridgeview Drive area. The gunman was eventually apprehended shortly after 10 p.m. along South Maple Street and lodged into Dawes County Jail. The weapon was also recovered. 

The State Patrol asked Chadron residents to shelter in place and lock doors until the situation was resolved. Chadron State College locked down a little after 7 p.m.
