"I want to clarify a report appearing in both the local print and broadcast media that alleged that Sheikhs closed DSTv and video dens in Mandera. The truth is that the Mandera district security committee met in September last year and resolved to close all video dens," the administrator said in a message sent out to the media.
According to Mr Seriani, the district security committee was targeting halls that show immoral videos, those that hide criminals and aliens, those that admit school children when they are supposed to be in school and those that operate without license or sell drugs.
