(AP)LOS ANGELES: Police arrested a man who tried to grab the boyfriend of Paris Hilton as the couple arrived Wednesday at a courthouse to testify against a suspect in an attempted break-in at her home last year. An Associated Press photographer and reporters interviewing the couple saw the man appear to get a hand on the neck of Cy Waits before being seized by a bodyguard and taken away. James Rainford, 36, was arrested on suspicion of misdemeanor battery on a person and was being held on $20,000 bail. The incident occurred as Hilton and Waits walked into a Superior Court building in Van Nuys to testify against Nathan Parada, 31, who is charged with attempted first-degree felony burglary. Hilton posted on her Twitter account that a “psycho intruder just punched Cy in the back of the head as we were walking into the court house.”
