RICHMOND -- In a violent 24-hour span, five people were shot in Richmond and police chased a driver who rammed a K-9 patrol car for more than 30 miles as occupants dumped firearms from the car along the way, authorities said Tuesday.

At 4:30 p.m. Monday, four people were shot -- two critically -- while driving in a car near Carlson Boulevard and Pullman Avenue, police said. The victims are known gang members, according to Sgt. Nicole Abetkov, and are not cooperating with police. All four are expected to survive.

Later that evening, at about 11:30 p.m. a driver rammed a K-9 patrol car after the officer attempted to pull the driver over, police said. The driver and three passengers then took off eastbound on Interstate 80, and threw three guns from the car near the Solano Avenue exit, police said. The chase continued across the Carquinez Bridge and into Vallejo, where occupants discarded another gun before exiting onto Highway 37, fleeing police with three flat tires, Abetkov said. The chase ended in arrests about six miles east of the Sonoma Raceway, after the California Highway Patrol placed a spike strip on the highway, police said. The four guns were recovered.

The four men are facing numerous charges, including gun charges and deadly assault on an officer with a car, Abetkov said. Police did not release the names of the suspects.

A juvenile boy was shot in the arm at around 1 p.m. Tuesday at Seventh Street and Chanslor Avenue, police said. No arrests have been made in the Monday or Tuesday shootings.
