KARACHI - Law-enforcement agencies have failed to apprehend culprits involved in the murder of 50 innocent citizens and so far have arrested only 85 alleged miscreants, mostly released by the courts on account of inadequate evidences, The Nation was told here on Wednesday. It is pertinent to mention here that City Police Chief Waseem Ahmed claimed to have arrest over 100 miscreants but the West Zone Police failed to produce all of them in the court. Most of the said miscreants had obtained bail from courts because sufficient evidence could not be presented against them. On the other hand, police and Rangers began operation in the Afghan Camp at Superhighway and arrested some 28 alleged miscreants besides recovering weapons from their possession. SP Gulshan-e-Iqbal Town Sohail Zafar Chatta claimed that arrested men were involved in several criminal cases including highway robberies. Sources privy to the matter told that police have recovered four TT pistols during the search operation. The police have also planed to conduct operation in Machchar Colony and its adjacent areas dominated by Pushtoons. Meanwhile, West Zone-I Investigation police have arrested 19 suspected miscreants in separate raids form different areas of North Nazimabad Town on charges of involvement in ethnic riots, setting the vehicles, shops and hotels on fire and damaging government and private property. "We had information that these men were plotting for more violence," SSP Khurram Waris said. The accused included Jaseem, Ateeq, Saweed Shah, Anwar, Ali Akbar, Naveed, Sohail, Khalid, Munawar, Obaidullah, Anawat Shah, Abu Bashar, Faisal Abdi, Saqib, Rahat, Zubair, Abdul Qadir, Saheen and Ameen. The police arrested them during raids at Raees Amrohi Colony, Pakistan Bazaar, Mominabad and North Nazimabad. Police also claimed to have recovered 11 TT pistols, one Repeater, three vehicles and ammunitions from the culprits. Several residents of the violence-hit areas claimed that miscreants had been using automatic weapons during riots but police were unable to recover even a single machine gun from them. CCPO Waseem Ahmed told The Nation that some 34 people were killed during riots and police would soon arrest the culprits involved in murders. However, he declined to answer further queries.
