Officers responded about 4:50 a.m. to the 2300 block of Jupiter Driver, where the 23-year-old had reportedly made his way to a home to see his ex, according to the Los Angeles Police Department.
Police found Conrad Hilton, brother of reality star Paris Hilton, inside a Bentley owned by his former girlfriend's father, police said. The officers then detained Conrad Hilton and the restraining order was confirmed.
After being arrested at 5:45 a.m., Hilton was taken to the LAPD's Hollywood station and booked on suspicion of grand theft auto and violating the restraining order, said LAPD Officer Jenny Houser, a spokeswoman for the agency. He was then transported to the sheriff's Metropolitan Detention Center in downtown Los Angeles.
Hilton was being held in lieu of $60,000 bail, according to online inmate records.
