South Bay police are investigating a kidnap and sexual assault case this weekend.
Santa Clara police got a 911 call after the victim flagged down a passing motorist on Saratoga Avenue and asked for help.
She told police she wasn't able to get a look at the man who attacked her.
The victim was driving a black Mercedes SUV. Palo Alto police are asking anyone who may have seen that vehicle early Saturday in either location to give them a call.
Witnesses can call the department directly at (650) 329-2413, send an anonymous text or email to email@example.com, or leave an anonymous voice mail message at (650) 383-8984.
