Pakistan Muslim League-Nawaz MNA Hanif Abbasi on Monday filed a petition in the Lahore High Court's Rawalpindi bench, challenging the investigation against him in the ephedrine scam. Issuing notice to the Anti-Narcotics Force (ANF), the court has sought the relevant record next week. Abbasi, in his petition, claimed that he acquired the drug quota as per rules and regulations but the ANF was taking illegal action against him.
