Islamabad: Pakistani prosecutors have again sought more time from an anti-terrorism court to serve an arrest warrant issued for former President Pervez Musharraf for not cooperating with investigators probing the assassination of former premier Benazir Bhutto.

Prosecutor Chaudhary Zulfiqar, who appeared on behalf of the Federal Investigation Agency, sought more time for serving the warrant for the former-President of Pakistan, currently living in self-exile in Britain. The court subsequently adjourned the case till April 23.

During the hearing held in Rawalpindi’s Adiala Jail for security reasons, the judge asked the prosecution about progress made in serving the warrant issued in February.

FIA Director Wajid Zia, who is the chief of the joint investigation team, told the judge that the British Home Department had failed to serve the warrant. Hence, the judge directed the FIA to contact the British government through the federal government to get the warrant served.

At the last hearing, the judge had summoned Zia to explain why authorities had been unable to serve the warrant.

The court issued the warrant in February after investigators declared Musharraf an "absconder" and told the judge that the former military ruler was not cooperating in the probe into the assassination.

Investigators have alleged that Musharraf's regime failed to provide adequate security to Bhutto after she returned to Pakistan from self-exile in 2007.
