LAHORE Punjab Minister for Law and Parliamentary Affairs Rana Sanaullah on Wednesday assured the House to carryout comprehensive investigation and early arrest of the killers of parents of Apex Courts senior judge Justice Javed Iqbal. Responding to the query of opposition legislator Mohsin Khan Leghari regarding preliminary investigations and efforts to arrest the culprits involved in the high profile murder at the Punjab Assembly floor, the law minister said that it would be too early to comment on the exact cause of death as the investigations were underway and all the aspects were under consideration. He assured the house that all the resources would be utilized for the arrest of the killers of the parents of Justice Javed Iqbal. He said that the investigations teams would look at the cases being heard by Justice Javed Iqbal to get the idea that whether any party having criminal background had gone to such extent. Chances of terrorist activity could not be ruled out as well, he added. He said that the police and investigation team was looking at the chance of offering resistance during the robbery. Record of the servants and relatives has also been gathered. It can be the result of some enmity, family rift, robbery, terrorist activity or result of resistance during robbery, he said. Meanwhile, talking to the newsmen outside Punjab Assembly, Rana Sanaullah said that unification bloc has majority and the leader of opposition should be from them. He said that out of 81 MPAs, unification bloc has the support of 46.
