The Anti-Narcotics Force (ANF) on Sunday recovered two kilogrammes of heroin from a passenger at the Benazir Bhutto International Airport, officials said.
ANF officials said the passenger, Ghulam Abbas, was due to travel on a Qatar Airlines flight to Italy via Doha on Saturday night when the drugs were recovered from his handbag during checking at the immigration counter.
Abbas, a resident of Chakwal, denied he had any knowledge about the presence of heroin in his bag, officials said.
The suspect was arrested and shifted to ANF headquarters. A First Information Report (FIR) was later registered against him under the Control of Narcotics Substances Act, 1997.
According to officials, the suspect will be presented before a local magistrate on Monday to seek his physical remand and hold an inquiry into the matter.
The incident comes as several cases have emerged of narcotics being recovered from flights originating from Pakistan.
Earlier this week, 20kg of heroin were recovered from a Pakistan International Airlines (PIA) flight at Islamabad airport.
