Conrad Hilton, the younger brother of Paris Hilton, has been arrested at his ex-girlfriend's Hollywood Hills home on suspicion of violating a restraining order, Los Angeles police say.
Officer Liliana Preciado says the woman called police Monday afternoon to say Conrad Hilton was trying to gain access to her property.
The 21-year-old was taken into custody without incident. He was later released on $5,000 bail.
Preciado says Hilton was under a court order preventing him from contacting his ex-girlfriend or members of her family.
His attorney, Robert Shapiro, did not immediately return a phone message seeking comment.
Hilton, the great-grandson of hotel magnate Conrad Hilton, also is awaiting sentencing on charges he attacked several flight attendants on a British Airways flight from London to Los Angeles last July.
