Since the sensationalized telephonic conversation between Khwaja and a Taliban operative was posted on the websites, Mir has been at the centre of the controversy. The information provided by Mir to the Taliban, was suspected to have caused the execution of Khwaja.
"We are going to the police and the Supreme Court in a few days to get a case registered against Mir as he was instrumental in the murder of my father by the Punjabi Taliban," said Khwaja's son, Osama Khalid.
"The person who was conversing with Mir on phone about my father was Usman Punjabi alias Umer. I recognise his voice as he
(Usman) had spoken to me on five or six occasions when my father was being held by the militants," added Osama. He also said that he has the record of the conversation between Usman Punjabi and Mir, made on Apr 19. Osama says that the video of his father's confessional statement, which was released to the media on Apr 23, is enough to lay hands on Mir.
Osama had requested Iftikhar Chowdhary, the Pak Chief Justice, to order a judicial enquiry to 'find out the truth'.
