"It would be very difficult to present Musharraf before the Court due to security concerns. The security alert says that he could be targeted like slain Punjab Governor Salman Taseer by his own bodyguards," Musharraf's lawyer Ahmed Raza Kasuri told reporters outside the court.
"So as per protocol each of the 1,600 security personnel have to be screened and it will take few weeks," he said.

Musharraf had on Tuesday failed to turn up for his indictment in the court citing security reasons and was summoned for today.
