ISLAMABAD, May 22 (Xinhua) -- Authorities at Pakistan's Islamabad airport have seized at least 20 kg of heroin from a Pakistan International Airlines (PIA) flight on Monday, local Urdu media reported.
Express News reported that the heroin was seized from PIA flight PK-785 which was ready to take off from Islamabad to London.
The flight was delayed for several hours due to the search operation that was conducted by the authorities on a tip-off.
Personnel from Airport Security Force and Anti-Narcotics Force took part in the operation and detained five staff members of the PIA.
The arrested people were shifted to an undisclosed location for investigations.
This is the second incident of the kind over the last two months. Earlier on April 4, the authorities seized 15 kg from a PIA flight in the country's southern port city of Karachi.
