According to sources, investigation into the case has started.
On May 22, Monday, over 20 kilogrammes of contraband was found hidden in the galley of the aircraft at Benazir Bhutto International Airport in Islamabad.
Pakistan Prime Minister's Aviation Adviser Sardar Mehtab Abbasi had ordered an immediate enquiry into the incident and posted Punjab Additional Inspector General Hussain Asghar as the enquiry head.
The airline has also decided that all international flights would be cleared only after thorough checking of the aircraft.
PIA’s spokesperson has informed that the aviation division has issued directives calling for the checking of every international flight by Anti Narcotic Force, PIA Securities, PIA Vigilance, Customs Intelligence and other institutions.
However, on Tuesday, a London-Lahore flight of the same airline was delayed for two hours.
