Cameron Diaz filed a police report Wednesday accusing a photographer of assault with a deadly weapon for allegedly driving his car at her, police said.

Diaz and her boyfriend, Justin Timberlake, were leaving a friend's home in Hollywood just after midnight Wednesday when a photographer who had been hiding in the bushes jumped out and tried to snap a picture of the pair, said police Officer April Harding.

The couple chased the photographer "a short distance," she said.

"The photographer got into his car and drove toward Diaz and Timberlake, causing Diaz to jump out of the car's way," Harding said.

No one was immediately arrested and no suspects have been identified.

"The investigation is in its initial stages," Harding said.

A law that took effect this year holds photographers who engage in criminal behavior to get a picture liable for three times the damages they cause, plus loss of any profits the published photo might generate.
