Police sources said the action was taken after a tip off that the city tycoon could be hiding in one of those premises. The operation was mounted on Friday by uniformed police personnel. Work at all the three factories has since stopped.However both actions have been greeted with protest from some people. Pastor Munyandamutsa, Rwigara’s elder brother and lawyer said that the closed factories and bank accounts are jointly owned by between Rwigara and other people. "There are other shareholders that have been affected by that decision,” he told The New Times. Munyandamutsa also said that there might be another reason behind Rwigara’s case. "I think there are other underlying reasons. All businesses are paralysed, we have nothing to do. Some of the closed companies don’t belong to Rwigara alone.” Rwigara escaped arrest a week ago at Kabusunzi when six policemen narrowly missed him. The policemen have since been locked up for failing the mission. The development followed a police search of Rwigara’s home in Kiyovu, an upscale Kigali suburb, according to Munyandamutsa. He said Police also interrogated him, Rwigara’s wife and driver.Police say it wants Rwigara answer questions related to his ill-fated construction in Kigali. Meanwhile two engineers – one for Nyarugenge District and another for the company that was constructing the building, Cogeco – who were arrested following the disaster were recently granted bail.
