Pakistani authorities on Tuesday posted a summons demanding that former military ruler Pervez Musharraf return from exile and appear before the country's top court on March 22.
The notice was glued to the gate of Musharraf's farm house on the outskirts of Islamabad after he failed to respond to repeated calls to appear over the December 27, 2007 murder of former prime minister Benazir Bhutto.
Musharraf, who has lived in self-imposed exile in London and Dubai since stepping down in 2008, delayed plans to return home this year indefinitely after the government warned he would be arrested upon arrival.
"Yes, I can confirm that a notice has been pasted on the main gate of Musharraf's farm house," Sheikh Naeem, a senior police official, told AFP.
The notice asks Musharraf to appear in the Supreme Court on March 22 with documents proving his identity as a Pakistani citizen.
Bhutto was killed in a gun and suicide attack after an election rally in Rawalpindi, the headquarters of Pakistan's army. Her party won elections two months later and her widower, Asif Ali Zardari, is president of Pakistan.
In 2010, a UN report said the murder could have been prevented and accused Musharraf's government of failing to provide Bhutto with adequate protection.
Pakistani investigators accused him of being part of a "broad conspiracy" to have his political rival killed before elections.
But at the time, Musharraf's government blamed the assassination on Pakistani Taliban chief Baitullah Mehsud, who denied any involvement and was killed in a US drone attack in August 2009.
