A man who identified himself as a freelance reporter was arrested outside the Los Angeles home of Brad Pitt on Wednesday, police said.

A housekeeper called police around noon after she saw a car blocking the actor's driveway, Officer Karen Smith said.

The man got out of the car and asked which house belonged to Pitt, the housekeeper told officers.

The 25-year-old reporter was arrested for investigation of trespassing and taken into custody on a "private person's arrest," Smith said. It will be up to the housekeeper to decide whether to press charges.

Neither Pitt nor his partner, Angelina Jolie, were home at the time.
