Justin Bieber and his father were "extremely abusive" to a flight attendant during a flight from Canada to New Jersey on Jan. 31, so much so that she had to take refuge in the cockpit of the private jet, according to an official report obtained by NBC News.

The report stated, "The flight attendant stated the passengers, including Bieber and his father, Jeremy Bieber, were extremely abusive verbally, and she would not work another flight with them."

According to multiple law enforcement sources, the plane Bieber and his 11-member entourage traveled in was so full of marijuana smoke that the pilots had to wear oxygen masks to avoid inhaling any smoke, which would cause them to fail drug tests.

"The captain of the flight stated that he warned the passengers, including Bieber, on several occasions to stop smoking marijuana," the official report said. "The captain also stated he needed to request that the passengers stop their harassing behavior toward the flight attendant and after several warnings asked the flight attendant to stay with him near the cockpit to avoid any further abuse."

As soon as the plane landed at Teterboro Airport in New Jersey, the private aircraft was met by DEA and Customs and Border Protection agents and police, who searched the aircraft before questioning Bieber separately from the other passengers. During the interview, Bieber admitted to smoking marijuana and drinking alcohol, but said he did not have any more marijuana.

No more was found on the plane and the crew decided not to take further action, so no charges against the 19-year-old were filed. Bieber was reportedly flying into New Jersey for the Super Bowl, which was held in the Garden State on Sunday.

Two days before the flight, Bieber turned himself in to Toronto police on an assault charge. He also was recently arrested in Miami on charges of DUI, resisting arrest and driving with an expired license. He is scheduled to be arraigned on Feb. 14.
