Former Inspector General Malik Naveed of Khyber Pakhtunkhwa police was presented in an accountability court on Saturday.
Naveed was taken to the court under tight security as his 10 day remand given by the court on December 4 was coming to an end.
The NAB presented a report on the weapon scam in the court.
The former IG is accused of corruption in a weapon scam case and was arrested by National Accountability Bureau on 20 November on charges of being involved in corruption in a multi billion rupees acquisition of weapons and vehicles for the provincial police department.
According to an earlier released NAB statement, the inquiry committee had discovered gross violation of procurement rules by the purchase committee in awarding tenders to contractors of choice.
