ISLAMABAD: Chairman National Accountability Bureau (NAB) Fasih Bukhari on Saturday said that the letter of Arsalan Iftikhar's Counsel was threatening and it would be considered as contempt of court.

A joint investigating team has formed into Arsalan's case and it will work according to the law. National Accountability Bureau will not become political weapon, he added.

During a press briefing, Fasih Bukhari said that due to mounted corruption, the national treasury is facing Rs6 billion to Rs8 billion loss per day.

So far, Rs 235 billion recovered and investigation on a number of other cases underway.

Bukhari told the media that a joint investigation team (JIT) including the FIA, NAB and police among others had been formed for investigating the Arsalan Iftikhar case and will be headed by the NAB director general (DG) Financial Crime Investigation Cell, as per the order of the Supreme Court and the Attorney General’s letter.

Bukhari said that although the Sharif brothers’ case could yield just Rs3 billion and the Swiss letter case, Rs6 billion but the case of former Oil and Gas Regulatory Authority (OGRA) chairman Tauqeer Sadiq could restore Rs55 billion to the treasury.

The chairman also said that the Ashraf was interrogated for 3 hours before he was made the prime minister and his name will likely to put in Exit control list (ECL).
