ISLAMABAD, July 18: The Interior Ministry has written a letter to the Qatar government, seeking extradition of Saifur Rehman, former chairman of the Ehtesab Bureau, to Pakistan, a private news TV channel reported on Wednesday.

The Federal Investigation Agency (FIA) had issued red warrants for Mr Rehman after he claimed he possessed evidence of President Asif Ali Zardari’s Swiss accounts and Gen (retd) Pervez Musharraf’s involvement in the $10 billion power plant scam in 2009.

The FIA had also formed a team for the arrest of Mr Rehman with the help of Interpol.

The allegations against Mr Rehman on the basis of which Qatar has been approached are not known, but it is believed that Mr Rehman faces the charge of conducting covert operations with the help of the Federal Investigation Agency during his days as the head of the now defunct Ehtesab Bureau when numerous citizens, including top businessmen and bankers, were picked up, kept under illegal detention and tortured.
