Paris Hilton's younger brother Conrad is in police custody after allegedly breaking a restraining order keeping him away from his ex-girlfriend Hunter Salomon, the daughter of his sister's sex tape partner Rick Salomon.

Hunter dated Conrad several years ago, and last month (May15), she was granted a temporary restraining order to keep him away from her after he allegedly began showing up at her home and trying to win her back.

However, on Monday (22Jun15), Conrad allegedly broke into her family's house in Los Angeles' Hollywood Hills, and according to TMZ.com, police officers swarmed the property and took Conrad into custody.

The incident comes days after embattled Hilton was sentenced to three years probation after pleading guilty to misdemeanor simple assault following a meltdown on an airplane last year (14).

He is also embroiled in a reckless driving case stemming from a car crash last year (14), and is scheduled to appear in court in Indio, California court on 14 July (15). He faces up to three years behind bars if convicted.
