On Tuesday, the Ministry of Interior approved a request by the National Accountability Bureau to declare their Lahore office a "red zone" and for security to be provided to the bureau on the day of PML-N Vice President Maryam Nawaz's hearing.

Maryam has been summoned by NAB on March 26 in connection with the Chaudhry Sugar Mills case, as well as the purchase of land in Raiwind.

As per sources, the Punjab government's sub-cabinet committee on law and order approved the declaration of the NAB office as a red zone during Maryam's appearance.

NAB had cited fears of a possible attack on its building the day the PML-N leader is expected to appear.

Sources claimed that approval has been granted for Punjab Rangers and police personnel to be deployed within the NAB office and surrounding areas on March 25 and 26.
