Conrad Hilton, the younger brother of Paris Hilton, surrendered to authorities on Tuesday after he was charged with assaulting and intimidating flight crew onboard a British Airways' flight last year. If convicted, the 20-year-old could face up to 20 years in federal prison.

The incident reportedly took place during a flight from London to Los Angeles last July after Conrad began disrupting flight service with a series of “profanity-laced tirades,” according to a U.S. District Court federal criminal complaint. He was released Tuesday on a $100,000 unsecured bond and was ordered to appear for arraignment on March 5. He had to reportedly surrender his passport and was ordered not to leave California.

Conrad voluntarily checked into rehab for a 30-day alcohol treatment program shortly after the incident took place, sources told TMZ. According to the criminal complaint, cited by The Los Angeles Times, drink service during the flight had been delayed by 40 minutes because of Conrad's disruptive behavior. He allegedly left his seat and was blocking flight attendants.

According to the court documents, Conrad called other passengers "peasants" and said that he would have killed one crew member if another passenger would not have calmed him.

“I could get you all fired in five minutes. I know your boss. My father will pay this out, he has done it before. Dad paid $300,000 last time,” Conrad reportedly told a flight attendant.

Conrad said he was angry over a recent breakup and wanted to smoke marijuana, The Associated Press reported. After Conrad fell asleep, the plane's captain ordered the crew to restrain him. He was reportedly handcuffed to his seat for nearly 90 minutes during the rest of the journey.
