A passenger has been arrested and charged after allegedly making a bomb threat aboard an international flight departing from Sydney Airport, prompting an immediate security response and the removal of the aircraft from departure procedures.

The incident occurred on Sunday as a Turkish Airlines flight was preparing to leave Sydney for Malaysia. According to authorities, a 44-year-old man from Montenegro attracted the attention of cabin crew when staff questioned him about a piece of electrical equipment he was carrying.

Police allege the man responded by telling crew members that the device was a bomb. The aircraft captain was immediately informed of the comment and decided to return the aircraft to the gate in accordance with aviation security procedures.

Reports indicate the object in the man's possession appeared to be a wireless phone charger rather than an explosive device. Nevertheless, airline and airport security protocols required authorities to treat the statement as a genuine threat until proven otherwise.

As a precaution, passengers seated near the man were instructed to move away from the area while security personnel assessed the situation. Officers from the Australian Federal Police subsequently boarded the aircraft and removed the passenger.

The man was arrested at the airport and later charged with one count of threatening aviation security. Under Australian law, the offence carries a maximum penalty of a $10,500 fine if the accused is convicted.

The accused was scheduled to appear before court on Tuesday.

Australian Federal Police Detective Superintendent Davina Copelin said airports operate under strict security arrangements and any statement suggesting the presence of a bomb or explosive device would be taken seriously.

She warned that comments some people may regard as jokes can trigger significant emergency responses, disrupt airline operations and divert security resources away from legitimate threats.

Authorities emphasised that false bomb claims are criminal matters rather than harmless pranks. Aviation security procedures require airlines, airport operators and law enforcement agencies to respond immediately to any indication of a potential explosive threat.

The incident caused disruption to the flight and required additional security checks before normal operations could resume. No injuries were reported and no explosive device was found on board.

The Australian Federal Police reiterated that maintaining safety across Australia's aviation network remains a priority and warned travellers that careless comments relating to bombs, weapons or threats can result in arrest, prosecution and substantial penalties.

Security experts note that even seemingly offhand remarks can trigger mandatory responses because authorities cannot risk dismissing a potential threat. As a result, passengers are regularly reminded to avoid jokes or comments relating to bombs or explosives while travelling through airports or aboard aircraft.

The investigation remains ongoing, with court proceedings expected to determine the outcome of the charge against the accused.
