LAHORE The City observed the worst gridlock on Saturday as the Kashmir Solidarity Day rallies blocked vehicular traffic on almost every road. The leading Lahore arteries were hit hard, as these were the target of a comprehensive police plan. According to this plan, all the leading roads were closed for all kinds of vehicular activities. Not less than 5,000 policemen, fully assisted by the personnel of other security agencies, were deputed on these roads to thwart any nefarious designs of the suspected terrorists. City Police Chief Mohammad Aslam Tareen and DIG Operations Rao Sardar Ali Khan said all the available resources were utilised to thwart unscrupulous elements. Aslam Tareen said that a modern network of close-circuit TVs had been installed at all important roads besides the walk-through gates at all entry/exit points. A sufficient number of police reserves, platoons and mobile teams of police commandos of elite force equipped with modern weapons and wireless fitted jeeps were conducting round the clock regular patrolling in all important areas of the city for maintaining law and order, he added. The control room at his office was also working round the clock to monitor the overall law and order situation in city. Moreover, the Jammatul Dawa also arranged its own security measures for the protection of its workers who participated in the rallies. Meanwhile, the CIA police picked a few suspected persons from different points for interrogation.
