UK and US helped nab alleged terror cell suspects
A tip-off from British and US intelligence agencies helped police thwart a terror plot to bring down a passenger plane.
Police are believed to have swooped on five properties across Sydney after allied intelligence agencies alerted them to the threat.
A father and son are among four men in custody.
Charges are yet to be laid as they’re questioned about alleged plans to use a homemade device to either bomb or gas hundreds of people on flight, believed to be Dubai-bound.
It’s understood one of the men is the brother of a senior ISIS figure.
Meanwhile, it’s been revealed, the son of one of the men had studied aviation management and socialised with pilots and airline workers.
Officials are keeping tightlipped on details of he investigation but the Prime Minister says the alleged plot was advanced.
EARLIER: The government has moved to bolster security at major Australian airports in the wake of an unprecedented terrorist plot on Australian soil.
Four men accused of plotting to bring down a plane with an improvised device will remain in custody while police go through evidence.
A magistrate has allowed federal police extra time to go through evidence seized during raids at five Sydney properties.
Travellers will now face increased scrutiny at domestic and international terminals.
Prime Minister Malcolm Turnbull says “security screening will take longer” but it was a small price to pay for safety.
“Travellers should arrive at terminals at least two hours before flights to allow ample time screening,” he said.
“They should limit the amount of carry-on and checked baggage as much as possible to ensure security screening is efficient.”
