It seems like Paris Hilton’s younger brother got himself into some trouble with the law, yet again. 21-year-old Conrad Hilton was arrested after he broke into his girlfriend’s home, according to law officials. He had been dating Hunter Salomon for quite some time, but he apparently started getting extremely obsessive and possessive with her. He even took it as far as threatening to kill himself. After their recent break-up, he broke into Salomon’s home in Hollywood Hills. The cops arrived to the scene ASAP and even helicopters swarmed the house. Hilton was arrested immediately and he is currently still in custody. Now here’s where things get weird. Remember Paris Hilton’s sex-tape from back in the day? Well Hunter is the daughter of Rick Salomon, the man who starred in the XXX-film with Ms. Hilton. Ah, the irony.
