The central information secretary of Pakistan Peoples Party, MNA Dr Nafeesa Shah, on Tuesday expressed concern over the release of five suspected Tehreek-i-Taliban Pakistan (TTP) members that were arrested for allegedly conspiring to assassinate PPP chairperson and former prime minister Benazir Bhutto in 2007.

"Pervez Musharraf, who is also involved in Benazir Bhutto's murder, was allowed to travel abroad. Now he is avoiding coming to Pakistan to appear before the court," Dr Shah regretted.

She expressed sorrow over the fact that the police officers who were found linked to the murder and handed court sentences were not only released on bail but reinstated into the force on their respective positions.

"Benazir Bhutto was a twice-elected prime minister. The release of those involved in her murder is tantamount to denial of justice," Dr Shah exclaimed.

The PPP leader warned about the consequences and said that such acts would encourage "the elements that constantly challenge the writ of the government and they will continue carrying out acts of terrorism".

Dr Shah said the release of the alleged murderers of an elected leader raises many important questions.

"It is on record that the government-appointed prosecutor in the murder case was killed in broad daylight," she said referring to the brutal killing of Federal Investigation Agency’s (FIA) special prosecutor Chaudhry Zulfiqar Ali on May 3, 2013.

Zulfiqar was shot multiple times by gunmen in Islamabad’s G-9 area as he was driving to attend the hearing in the murder case of the former prime minister.

On Monday, the two-member LHC bench accepted the plea of the father of Aitzaz Shah, one of the five suspects, who said he had nothing left to pay the fee of his lawyers. The court ordered their release on submission of surety bonds worth Rs500,000 by each suspect.

The bench further directed the authorities concerned to ensure their presence at every hearing of the case.

Earlier, an Anti-Terrorism Court (ATC) in Rawalpindi in its Aug 31, 2017, verdict had acquitted the five TTP suspects and handed down 17-year jail terms to two police officers for criminal negligence in ordering the hosing down of the crime-scene and their failure to provide security to Ms Bhutto. The ATC also declared retired Gen Pervez Musharraf an absconder in the case.
