LAHORE - City police have stepped up snap checking and security of sensitive installations at important locations in order to avoid any untoward incident, police sources said on Friday. The police across the provincial metropolis have been directed to remain on high alert for maintaining law and order in their respective areas. The police officers have been directed to take effective precautionary measures, especially in the crowded public places to prevent incidents of terrorism and subversion as police deployment in plainc-lothes has been enhanced in the sensitive areas to keep a vigilant eye on the activities of the miscreants. The police have also intensified patrolling around railway stations, bus terminals, bus stops, markets, cinema halls, hotels, mosques, imamb-argahs, churches and other important places of the City.
