The other three accused produced before the court of Judge Ali Gohar included Accounts Office employee Sher Baz, contractor Sartaj Khan and a relative of main accused Faheem Moeen Khan.

Earlier, Head Clerk of Communication and Works Department and main accused Qais Iqbal and his wife had also been sent to jail after completion of physical remand.

According to NAB sources, 27 people have been arrested in this case so far. Investigations revealed that officials of the Communication and Works Department in Upper Kohistan, in collusion with officers of the Accounts Office and National Bank, carried out fake withdrawals from the national treasury.

These funds were withdrawn in the name of various projects and contractors who had not done any work. Officials said more than 37 billion rupees were illegally withdrawn from account number G-10113 in the name of contractors' security deposits by the main accused and several others.

According to NAB, the accused misused their positions, prepared fake documents and received huge sums from the national treasury. The scandal involves officers of the Accounts Office, the Communication and Works Department, banks and several private contractors.

The court has endorsed several orders issued by NAB and ordered the freezing of dozens of properties, including residential houses, commercial plazas, valuable plots, vehicles, cash and foreign currency.

The 38 frozen properties include those attributed to another key accused, Muhammad Riaz, and his relatives. Muhammad Riaz, previously a cashier in a bank, later became a contractor. After resigning, he established construction companies in the names of his six brothers and later registered all of them under his own name.
