A PIA flight PK-203 was ready to leave for Dubai yesterday from the airport here when the ANF staff got it vacated on information that a huge quantity of heroin had been concealed in the aircraft, officials said.
After a thorough search of a couple of hours the ANF team seized 6 kg heroin which is worth over Rs 60 million from the toilet of the aircraft, they said.
According to officials, ANF arrested at least 12 PIA employees today and launched a thorough probe into the matter.
After investigation if these employees are found guilty, strict action will be taken against them, he said.
During the last few years there has been a rapid rise in the number of cases in which the PIA employees caught red-handed while smuggling different items like drugs, cigarettes, mobile phones, illegal passports and laundered money abroad.
In some cases the PIA employees were caught at Pakistani airports and in others they were intercepted and arrested in other countries, mostly in the European destinations.
