The political administration launched a crackdown against criminals in the area on Wednesday, and arrested 12 suspects under the Frontier Crimes Regulation and confiscated six vehicles. The crackdown -- launched against offenders from Sultankhel tribe, a sub-tribe of Haleemzai -- was ordered after the Haleemzai tribe failed to surrender men wanted by the government. Meanwhile, security forces launched a search operation in Kulachi tehsil to hunt down people facilitating local Taliban. The forces have so far arrested Asad Sheikh, brother of local Taliban leader Karamad Sheikh.
