Local media reported that two people were killed and at least two others were injured in a shooting Tuesday afternoon near a polling place in the southern California city of Azusa.

Azusa police urged residents to stay out of the area and seek shelter, the Los Angeles Times reported. Officer Jerry Wilson of the Azusa Police Department said it was unclear whether any officers were injured in the shooting. 

A Los Angeles County police official said the investigation is ongoing. She would not confirm the reports any deaths and injuries. She said police are looking for one suspect.

Two polling stations were “impacted” by the incident, county Registrar-Recorder Dean Logan said on Twitter, ABC7 reported. 

The location was close to an elementary school and middle school, but no one at the schools was hurt. Both campuses were placed on lockdown according to the Azusa Unified School District.
