Conrad Hilton has been ordered by a Los Angeles judge to go to a rehabilitation center for substance abuse treatment for 90 days instead of serving a prison sentence, according to the Associated Press.

The younger brother of Paris Hilton and Nicky Hilton was able to avoid being sent to prison even after authorities had asked for him to be jailed for 60 days.

The City News Service reported that the hotel heir should be sent to prison because of his probation violations, failed drug tests and previous treatment programs he went to, according to Wonderwall.

Hilton turned himself in to the authorities in February 2015 for misdemeanour conduct on a British Airways flight in July 2014.

A plea agreement reveals that all throughout the flight, Hilton used the bathroom to smoke tobacco and marijuana, as well as intimidating and threatening flight attendants who were not named, as HNGN previously reported.

Months later, Hilton was arrested again for violating a restraining order that was taken out against him, where he broke into an ex-girlfriend's Hollywood Hills home. He was released on bail for $5,000.
