British Airways crew members were forced to restrain a passenger on board a flight from London to Dubai after he "went berzerk" and threatened to blow up the plane, a report said.

According to a report in The Telegraph, a male passenger became aggressive about five hours into BA flight 105's journey and began fighting with and spitting at the staff, the father of one of the passengers had claimed.

After the 45 minute ordeal, five crew members and another passenger had to handcuff him and cover him with a blanket because he reportedly began spitting at everyone.

Steve Penk, whose daughter witnessed the chaos on board, tweeted about the incidents. “…some guy went berserk on board 5 hrs into the flight claiming he had a bomb and everyone was going to die. It took 5 crew and the help of another large passenger to restrain him.”

“My daughter Natalie says the guy was literally screaming and shouting he couldn't breathe. He shouted everyone was going to die. Absolutely terrifying,” Penk tweeted.

The flight landed in Dubai as scheduled and the man was handed over to the Dubai police.

Penk later posted: "The BA crew on board were amazing apparently. Thank you to all the crew on BA flight 105 last night x."
