It looks like a cement block ended the chase between police and the driver of a black Dodge Challenger. A red vehicle involved in the chase was an unmarked police car.
It all started in the Bayview when police suspected the driver had a weapon. The driver took off leading police through the Taraval District where police say the driver tried to ram a patrol car.
They also say he struck a civilian vehicle and injured an officer who was on foot.
One officer fired a shot into the car but did not hit the suspect.
The chase finally ended in the Haight near Golden Gate Park. No weapon was found.
Police say there are a lot of separate crime scenes along the way so it will take a while to wrap up the investigation.
