Officer William “Billy” Collins worked part-time for the force in Doyline, a village in Webster Parish that is located about 22 miles east of Shreveport in the northwest corner of the state.
Collins also worked as a full-time corrections officer, authorities said at a news conference.
A suspect was taken into custody after initially barricading inside a mobile home, authorities told KTAL-TV of Shreveport.
The suspect was transported to a hospital with life-threatening injuries, KSLA-TV reported.
Explosions and gunfire were heard from the scene just before 11 p.m. Friday, the KTAL report said.
Louisiana State Police posted an alert on Facebook, asking residents to stay away from the crime scene, to which personnel from numerous law enforcement agencies had responded.
The officer was shot around 8 p.m., not far from Doyline High School, the station reported. After being wounded, he was airlifted to Ochsner LSU Health in Shreveport, where he later died, authorities said.
