A Finnish passenger accused of making a hoax bomb threat on a Cathay Pacific flight in February has appeared in court in Hong Kong.

Antti Oskari Manselius, 23, is accused of wielding a chocolate bar "like a sword" on 14 February and demanding that the plane be diverted so he could attend the Winter Olympics.

Mr Manselius appeared in court yesterday charged with disorderly behaviour on an aircraft and for "communicating false information as to the existence of a bomb" during the Amsterdam-Hong Kong flight.

The court heard that he armed himself with a large Toblerone chocolate bar and told flight attendants he was "robbing" the plane.

The South China Morning Post reported that he demanded that they divert to the Russian resort of Sochi where the Olympics were taking place.

Mr Manselius, who was said to have approached the cockpit around six hours into the flight, pleaded not guilty, claiming that he was only making "fun and jokes", the Post said.

"He said, I am robbing the plane now. I want to see the Olympics in Sochi and I need to get off the plane now," Leung Hiu-lun, a flight attendant, told the court.

"He made me feel like he was trying to endanger the aircraft," Ms Leung said.

The flight attendant added that Mr Manselius made a bomb threat, but the crew - believing he was mentally unstable and was joking - did not search the plane.

Ms Leung's colleague Luk Ka-chun told the court Mr Manselius held the Toblerone bar "like a sword".

The passenger was ordered back to his seat and his hands and legs were cuffed, the court heard. He was arrested when the plane landed in Hong Kong.

The trial has previously heard that Mr Manselius suffers from mental health problems and that he was transferred to a psychiatric facility after his arrest, the Post said.
