Conrad Hilton, the younger brother of Paris Hilton, surrendered to the FBI on Tuesday after allegedly threatening to kill British Airway flight attendants and calling passengers “peasants” during a flight from London to Los Angeles in July.

Hilton, 20, is accused of assaulting and intimidating the crew to the point where it interfered with their ability to perform their duties, according to a U.S. District Court criminal complaint obtained by PEOPLE.

Witnesses on the flight reported that Hilton screamed profanities at the crew and passengers, including, “I am going to f—ing kill you!” and “I will f—ing own anyone on this flight they are f—ing peasants,” according to the complaint.

At one point, witnesses said Hilton was punching the bulkhead of the plane and he was so out of control that children on the plane were crying.

Witnesses also told officials that Hilton grabbed a flight attendant’s shirt and said, “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,” per the complaint.

Hilton’s attorney Robert Shapiro confirmed to TMZ, which first reported the incident, that Hilton had taken a sleeping pill before the flight.

Hilton also smoked a cigarette and later marijuana in a plane bathroom, according to the complaint.

When Hilton fell asleep, the co-pilot told the FBI that he assembled a “restraint team” of crew members, and Hilton was handcuffed to his seat.

Hilton was charged in federal court Tuesday, MSNBC reports.

If convicted of the charge, he faces up to 20 years in federal prison.
