Islamabad (Agencies): Pakistan Prime Minister Yousuf Raza Gilani's son has been formally summoned by investigating officers probing the alleged Haj pilgrims’ accommodation scam.

The summons was issued to Abdul Qadir Gilani after he could not appear before the Federal Investigation Agency (FIA) on Monday to record his statement regarding the scam.

The Prime Minister’s son has been blamed of receiving Rs 20 million as kickbacks in the scandal involving multi-million rupee that has already cost two federal ministers their jobs.

FIA chief Waseem Ahmed told The Express Tribune newspaper that a notice had been issued to Qadir Gilani "asking him to appear before the Joint Investigation Team set up for the Haj scam".

The daily quoted its sources as saying that Abdul Qadir has been threatened with "perpetual arrest warrant" if he fails to appear for questioning.

A warning from the FIA's legal directorate was attached to the notice summoning Qadir for questioning, the report said.

The investigation agency summoned Qadir to record his statement in line with an order issued recently by the Supreme Court, which is hearing a suo motu case on the Haj scandal.

Former Religious Affairs Minister Hamid Saeed Kazmi, who is also an accused in the case, is presently free on interim bail after a court in Islamabad issued a warrant for his arrest.

The notice also includes a questionnaire consisting of about a dozen queries.

Hours after the notice was issued by the FIA on Monday, Hussain Asghar, the head of the investigation team probing the scam involving Gilani's son, was removed from the panel.

Zain Sukhera, a close friend of Abdul Qadir who has also been connected to the scam, resigned from his post of consultant with the Information Technology Ministry on Monday.

Sukhera has been accused of obtaining a sham LLM degree, on the basis of which he was appointed to the post.
