One passenger, who was travelling alone said she was seated near family members of the two men, who she understood are brothers.

The witness, who would like to remain anonymous, told Sunrise that she was aware of the men hours before their outburst.

“From the moment they boarded the aircraft, they appeared extremely agitated and restless,” she said.

“They were repeatedly getting in and out of their seats, moving around the cabin and into my personal space, and touching or moving my belongings.

“They were also repeatedly rummaging through their luggage and saying they were looking for items they had apparently misplaced.”

The witness told Sunrise that the two men began fighting with each other six hours into the 14-hour flight, before they allegedly turned on cabin crew.

“A very strong passenger immediately stepped in and restrained one of the brothers, while members of the cabin crew restrained the other,” the witness said.

"The men would not comply with instructions from the crew, and ultimately had to be restrained.

“One of them eventually calmed down and remained relatively quiet for the rest of the flight. The other remained extremely angry and agitated.

“He was yelling, spitting, kicking and headbutting a flight attendant.”

That is when she said several other male passengers stood up to intervene and assist cabin crew in restraining the man.
