San Mateo police detectives headed to a home the 1400 block of Newbridge Avenue at about 10:10 a.m. today to serve a "high-risk" search warrant, Sgt. Bob Szelenyi said.
The person named in the search warrant was on parole for assault with a deadly weapon, and the house where the warrant was served was believed to contain known prison gang members, Szelenyi said.
As officers served the warrant this morning, the suspect exited the house and got into the passenger seat of an occupied car parked outside, Szelenyi said.
Police tried to stop that vehicle but the driver wouldn't yield and instead rammed an occupied police car, Szelenyi said.
At that point, a San Mateo detective shot the driver, Szelenyi said. The driver was treated at the scene and then airlifted to Stanford Hospital in critical condition.
The person named in the search warrant was detained, Szelenyi said.
Police have not released the name or age of either suspect.
