A park service ranger saw a suspect breaking into a car on Conzelman Road in the Marin Headlands at about 8 p.m. but when the ranger tried to stop the suspect, he jumped into a black Mercedes and the Mercedes driver sped off, NPS spokeswoman Alexandra Picavet said.
During the escape the Mercedes smashed into two park ranger cars and then got onto the Golden Gate Bridge but rear-ended another car at the toll plaza, Picavet said.
The suspects got out of the car and ran away. Park service rangers, with the help of San Francisco police and the California Highway Patrol, set up a perimeter to search for the suspects, Picavet said.
Officers are searching from the Fort Point area into the residential areas of the Presidio, Picavet said. Both suspects remain at large.
