A California Highway Patrol officer was shot and wounded Thursday afternoon while serving a warrant in Roseville. The suspect then took two hostages and one was killed.

The CHP officer was treated and released at a local hospital.

A spokesperson with the Roseville Police Department said the CHP officer serving a warrant was shot around 12:30 p.m. This prompted other law enforcement agencies to come help, KCRA reports.

Roseville police said as those other officers arrived, the suspected gunman shot at them while running away. The gunman then took two hostages before he eventually surrendered.

The two bystanders taken hostage were hit by bullets, police said. One of them died at the scene, and the second one was sent to a hospital with unknown injuries and is expected to survive.

Roseville police originally said the gunman shot both hostages, but they have since clarified their language to say, "It is believed the suspect shot both hostages during the incident."

Police said the suspected gunman is in custody and was transported to a hospital with gunshot wounds. His condition is unknown.
