A United Airlines flight had to divert and make an emergency landing after a passenger allegedly bit a passenger's ear before assaulting other passengers.

In a statement from United, they confirmed to Fox News that flight 728 was diverted to the airport in Charleston, South Carolina because of the incident. It was originally planned to fly from Newark to Miami.

The Charleston County Aviation Authority Police Department said the passenger became "restless" and "very agitated" after he went to the bathroom mid-flight.

He then reportedly got up to "retrieve what appeared to be pills from his carry-on bag in one of the overhead bins."

When he sat back down, he started screaming and thrashing around. The passenger next to him put his arms up to keep from being hit, but the man still hit him, breaking his glasses.

He also bit the passenger's ear a la Mike Tyson.

The whacked out guy also assaulted two other passengers before a doctor onboard injected him with benadryl in his butt to sedate him.

When police arrived on the plane after it landed, the man was "face down on the floor of the aircraft being restrained with his hands behind his back with zip ties and a belt."

They found 1.5 grams of meth in his pocket, so he was arrested and charged with possession with intent to distribute the drug.
