A Baton Rouge police officer was injured late Sunday night when a suspect fired several rounds into a marked police unit in the area of Thomas H. Delpit Drive and Lettsworth Street, said Baton Rouge police spokesman Sgt. Don Coppola Jr.

Coppola said the officer's injuries appear severe but not life threatening.

Sgt. L'Jean McKneely, another police spokesman, confirmed early Monday that the suspected shooter was being detained. He was taken into custody following a pursuit that ended when he surrendered to police. 

Officers ended up investigating three scenes in connection with the incident.

Police said the suspect shot up a car belonging to one of his relatives around 10:45 p.m. in the 2200 block of Thomas H. Delpit Drive, which triggered the initial shots fired call.

No one was injured in that shooting but the suspect left the scene, ending up on Lettsworth Street where he fired several rounds at the police unit — the first unit to arrive there. The injured officer was struck with glass and shrapnel from the car, but appeared to have escaped the bullets themselves, Coppola said. 

The shooter then left that scene too and after a short pursuit was taken into custody on West Harding Street near Highland Road where he ultimately surrendered. It was not immediately clear whether the shooter was injured. 

Baton Rouge police initially said Louisiana State Police would handle the investigation per protocol for an officer-involved shooting. But several hours into the investigation, authorities announced that Baton Rouge police would actually be handling the investigation after all.  

Coppola said it did not appear that the officer had fired his weapon during the altercation. 

At the scene on Lettsworth Street, investigators focused on a police unit parked in the street. The driver's side door of the vehicle appeared to have been damaged by gunfire.

Authorities were questioning the suspect early Monday and anticipated booking him into Parish Prison later on.

Speaking at the scene, Coppola described "a tragic incident that could have turned out worse" and said the events serve as a reminder of the dangers police officers face in their job. 

"This is something that has to stop," he said.

More details to come.
