It was perhaps because of the failure of police and Rangers that the Sindh government gave police powers to the Frontier Constabulary, allowing it to carry out raids and make arrests. The Rangers are already enjoying police powers but they have not been able to rein in the killers.

According to police sources, two bodies were found from a compound in Bhempura area of old city while the other two bodies were found from Jamshed Road and Garden areas.

All four people were abducted and later tortured to death, police said. The bodies were taken to Civil Hospital for further investigation.

Heavy contingent of Rangers have been deployed in Landhi 89, Old Sabzi Mandi, Metrovile, Qasba colony, Orangi town and other areas.

Rangers officials have set up temporary pickets on the roads of Karachi and in the tense areas and started snap checking.

Meanwhile, Rangers conducted operation in Orangi town and apprehended several accused. Rangers cordoned off Katti Pahari, Gulfamabad and Bukhari colony and conducted search operation for four hours. More than 40 Rangers mobiles and armoured vehicles took part in the operation.
