The city of Fremont is on a "city-wide lockdown," reports KRON4, with residents being told to stay inside and a "shelter in place" order having been issued. Police officers from multiple agencies are currently searching for at least one suspect in the shooting of at least one police officer earlier today.

According to ABC 7, a police officer driving a patrol car was struck by a car around 1:30 p.m. today and attempted to make a traffic stop, but the driver then backed into the officer's car. Shots were soon fired and the suspect (or suspects) fled.

It is unconfirmed if the officer was struck by the car and shot, if the officer was able to return fire, or if the officer was only injured by the car, as the Chronicle reports. That officer was transported to the hospital.

Police began searching for the suspects, and KRON 4 reports that officers found the "suspect vehicle" at Washington and Roberts streets. A suspect reportedly opened fire — striking a second officer.

Fremont Police tweeted out a series of updates about the case, including that "shots were fired after vehicle backed into officer's car. The officer was injured and suspects fled on foot." Police describe the suspect as a "Hispanic male adult, approx. 6' wearing [SF Giants] shirt/shorts."
