SAN JOSE (CBS/AP) — Authorities say the San Jose Police Department website and other city web pages were shut down intermittently for several days after being targeted by a cyber attacker.

The San Francisco Chronicle reports Wednesday that the websites were hit last Thursday after large amounts of traffic are deliberately sent to the sites to congest them and shut them down. No arrests have been made.
