A security breach by Delta Airlines caused travel chaos for passengers at Victoria International Airport on Saturday.

At approximately 8 a.m., Delta Airlines cancelled one of its flights, airport officials tell CTV News.

It then mistakenly returned checked luggage to the affected passengers in the holding room where checked luggage isn’t allowed.

The director of security and terminal operations, Ian West, says the mistake forced officials to evacuate the holding area, clear it of the checked bags and send passengers through security screening a second time.

We appreciate the patience and cooperation from all passengers as we rescreen everyone after a security breach this morning. — Victoria Int Airport (@Fly_YYJ) October 28, 2017

Staff say flights at the airport were delayed from about 8 a.m. to 10 a.m.

Transport Canada has been advised of the breach and will conduct an investigation.
