At least 1 person is dead and 3 people are injured after a gunman opened fire at a polling station in Azusa, California, a northern suburb of Los Angeles. Two nearby polling stations have been placed on lockdown. Los Angeles County Sheriff’s Capt. Jeff Scroggin said police were dealing with at least one suspect who was heavily armed.

The shooting was first reported around 2pm local time (5pm eastern), and there are reports it may have involved a police officer, and that the suspect is still at large.

Few details were released about the shooting, which occurred sometime after 2 p.m. in a residential neighborhood in the area of Fourth Street and Orange Avenue, said Officer Jerry Willison of the Azusa Police Department.

Willison declined to provide the location of the shooting for the safety of the officers and the victims, he said.

Azusa police urged residents to stay out of the area and asked all residents to shelter in place.

It was unclear whether any officers were injured in the shooting, Willison said.

Azusa Union School District issued a lockdown for Slauson Middle and Mountain View Elementary schools about 2:15 p.m., officials said. A nearby daycare center and preschool was also locked down.
