"Chaudhary Aslam is a true martyr and hero of the nation as he never bowed down before the Taliban," Bilawal told the widow and sons of the slain officer, becoming the first politician to visit their residence.
The son of former President Asif Zardari and former Prime Minister Benazir Bhutto has in recent months entered the political mainstream with a stream of hard-hitting statements against the Taliban and his political opponents.
His tweets have snowballed into major controversies and upset his opponents in the past.
Bilawal said Aslam was a brave and courageous officer who laid down his life for fighting against terrorists.
