An Australian man was fined by a Singapore Court after he jokingly made a "bomb" comment while on board a flight to Indonesia.

Riccardo Paulin, 65, pleaded guilty Tuesday to charges of raising a false alarm about a terrorist act.

According to the Straits Times, Paulin asked a SilkAir flight attendant, "Where do you keep the bomb?" after he could not find space in the overhead lockers.

The pilot was informed and Paulin was removed from the plane.

Paulin was charged under the United Nations anti-terrorism regulations, which carry a maximum fine of S$100,000 ($6,423 USD) or up to five years in jail or both.

He apologized to the court for his remark, saying it was meant as a joke.
