Conrad Hilton has been sentenced to three years probation.
The 21-year-old socialite was also ordered to pay a $5,000 fine, undertake 750 hours of community service and have mental health and substance abuse treatment at a hearing yesterday (16.06.15) after previously pleading guilty to a misdemeanor count of simple assault, which stemmed from an incident on board a British Airways flight from London to Los Angeles last July.
During his court appearance, the hotel heir - who reportedly branded other passengers "peasants" and threatened to kill air crew during an onboard rang - apologised for his conduct and vowed it wouldn't happen again.
Court documents had shown drink services were delayed almost an hour due to Conrad's outburst, while the plane's captain ordered he be "restrained" to stop any further trouble.
The files stated: "The captain authorised crew members to restrain him to his seat for the descent and he was ultimately handcuffed to his seat."
Conrad's sentencing came after he was placed under house arrest last month until his sentencing after breaking his $100,000 bail by failing a drugs test and smoking marijuana.
Newly released court documents filed in California on 30 April state: "The conditions of defendant Conrad Hughes Hilton's pretrial release in this matter are hereby amended to include a curfew restricting defendant Conrad Hughes Hilton to his residence every day from 10:00 p.m. to 5:00 a.m. All other pretrial conditions will remain in effect as previously ordered."
