An 11-year-old boy has managed to sneak on board a flight to Rome from Manchester Airport without a passport or boarding pass. Liam Corcoran passed through security on his own without being checked, before making his way on to the Jet2.com flight on Tuesday, after he ran away from his mother during a shopping trip at Wythenshawe Civic Centre and made his own way to the airport. A Manchester Airport spokesman said: “This extremely serious matter is now being urgently investigated by officials from the airport and airline. “It is clear that documentation has not been checked correctly at security and the boarding gate. “The boy went through full security screening so the safety of passengers and the aircraft was never compromised. “We are now making preparations to ensure that his return to the UK is handled sensitively to avoid any distress.”
