Political administration of Khyber Agency on Sunday arrested around a dozen tribesmen belonging to Loi Shelman and impounded three vehicles used in blocking a road between Shinwari and Loi Shelman. The action was taken after residents of Loi Shelman set up an illegal check post in Loi Shelman. Tribes of Pero Khel and Sheikhmal Khel had also erected chains on a road to extort money from transporters. These check posts have now been removed.
