International flights from Melbourne Airport delayed after security breach A SECURITY breach has forced the evacuation of the international departure lounge at Melbourne Airport. About 2000 passengers were told they had to go through security screening again after the incident. A Melbourne Airport spokeswoman said it was a "minor security breach" but would not elaborate further. "We do not comment on the detail of security breaches," she said. But I can say that there is nothing to be concerned about. Are you there? Contact our newsroom on 9292 1852. All passengers are being re-screened as per standard security procedure. She said some flights would be delayed following the breach. Passenger Karina Gibbs posted on Twitter: "Not happy Jan! Security breach at Melbourne airport! International flights evacuated for rescanning and checks. A Werribee man also took to the social networking site to vent his frustration: "#Melbourneairport fail - minor security breach = little info, huge lines, unknown whether flying today." Melbourne's Leanne O'Donnell was meant to depart on her US-bound flight at 11.15am and tweeted: "Not going anywhere quickly. Major logistical exercise to rescreen this many people.
