Four Baton Rouge Police officers were involved in a shooting late Friday that killed an armed man after a chase that ended in West Baton Rouge Parish, a police spokesman said.

"It appears that all four officers fired their weapons," police spokesman Sgt. Don Stone said Saturday in a phone interview.

The incident started about 11:15 p.m. Friday when a Baton Rouge police officer in a fully marked police car tried to pull over a motorist for a traffic violation on Airline Highway near Florida Boulevard, Stone said Saturday in a news release.

Stone did not elaborate on what the violation was.

The driver instead refused to stop, and led police on a pursuit over the Old Mississippi River Bridge into West Baton Rouge Parish, the release says.

At some point, three more officers in police cruisers joined the chase, Stone said.

The pursuit, which never reached high speeds, continued west on Highway 190 past Highway 415. About a mile west of the intersection of highways 190 and 415, the driver pulled over on the right shoulder of Highway 190, the release says.

As the man got out of his small pick up truck as ordered, the "officers observed a gun in his hand," Stone's release says.

The police ordered the man to drop the gun. When he refused to comply, the "officers shot him," the release says.

The only information Stone said he could release about the driver is that he was a white man and that he was the only person in the pick up.

The West Baton Rouge Parish Coroner's Office removed the body from the scene, the release says.

The four officers, who are assigned to the Uniform Patrol Division, were placed on paid administrative leave. Stone's release says that is standard practice when an officer is involved in a shooting.

State Police will be the lead agency investigating the shooting, Stone said. The Baton Rouge Police Violent Crimes Division and the West Baton Rouge Parish Sheriff's Office helped with the on-scene investigation.
