LAHORE - The National Accountability Bureau (NAB), once again, has called some key politicians to appear before “investigators” as political parties launch countrywide campaign ahead of general elections 2018.

Reportedly, PML-N President Shehbaz Sharif, PTI leader Aleem Khan and PML (Q) leader Moonis Elahi are again summoned by the anti-graft body in connection with different corruption cases.

The latest move comes one day after the NAB officials arrested Qamar-ul-Islam Raja, a candidate of the PML-N for the National Assembly seat from Rawalpindi. Former MPA Raja was detained by NAB on Monday on corruption allegation in Saaf Pani Company case.

But, he strongly denied the charges and claimed that the authority never issued him any notice before his arrest.

More interestingly, the NAB Bureau in Lahore rarely issues Press releases. Instead, a few reporters are fed the “news items” and they are forced to report the story through sources.

According to a private news channel, PML-N leader and former Chief Minister Shehbaz Sharif has been summoned by the authority for July 5.

Similarly, PTI leader Aleem Khan is bound to appear before the NAB investigators in Lahore on July 13.

However, Chaudhry Moonis Elahi, PML-Q leader and son of former Punjab CM Chaudhry Pervaiz Elahi, has been asked to appear before the authority on July 13.

Former Chief Minister Shehbaz Sharif has been summoned by NAB in connection with multi-billion corruption scandal involving Saaf Pani Company while Aleem Khan and Moonis Elahi are being summoned for having off-shore accounts.

It was not clear yet whether these political leaders will appear before the authority or not.

In the recent past, they were summoned by NAB in the similar cases but they skipped the proceedings on some occasions. However, they submitted their replies to the investigators at NAB headquarters earlier.

On the other hand, security has been heightened at the NAB headquarters in Lahore following threats of “bomb attacks” by unknown quarters.

Paramilitary troops were seen guarding the NAB offices on Monday in Lahore. Earlier, NAB Chairman Justice (Retd) Javed Iqbal claimed that the NAB had received threats that its headquarters would be blown up with explosives.

In Lahore, dozens of policemen are also deployed in and outside the headquarters of the national anti-graft body in addition to the Pakistan Rangers personnel. The police patrolling has also been intensified around the NAB offices to ward off any possible assault.

Shehbaz Sharif on Monday skipped appearance before the anti-corruption body in Lahore and rushed to Karachi to formally launch the election campaign from the port City.

Reportedly, the NAB authorities had asked the former Punjab Chief Minister to appear before the combined investigation team at the NAB headquarters in connection with the alleged Saaf Pani scandal on Monday.

The NAB authorities on Tuesday again summoned the PML-N President to appear before the investigators on July 5 after he failed to appear before the NAB team on Monday.

The Punjab Saaf Pani Company is one of the 56 public sector companies established by PML-N government in Punjab since 2008.

Last year, NAB chief Javed Iqbal had ordered a full-fledged probe into the 56 companies over allegations of embezzlement, corruption and irregularities. Several key officers of the Saaf Pani Company are already arrested by the authority over corruption allegations.
