An Australian man was charged in Singapore on Saturday for making a bomb threat on board a Perth-bound plane that forced the aircraft to turn back under fighter jet escort.

Hawkins Kevin Francis, 30, faces up to 10 years in jail or a fine not exceeding Sg$500,000 ($356,000) or both on conviction.

Flight TR16 operated by Singapore budget carrier Scoot, the low-cost arm of Singapore Airlines, was forced to turn back to the city-state an hour into the journey on Thursday after the threat was made.

Singapore's air force scrambled fighter jets to escort the aircraft back and the plane landed safely. Police said the threat was false.

Francis, who was not identified at that time, was arrested by police who boarded the plane.

He allegedly told a member of the cabin crew "I have a bomb" during the flight, according to the charge sheet.

He also "uttered the word 'bomb' repeatedly" to another cabin crew member.

Despite knowing the threat to be false, Francis wanted to make the cabin crew believe "that a terrorist act will be carried out." He committed an offense under the United Nations (Anti-Terrorism Measures) Regulations, the charge sheet said.
