Longtime Ugandan President Yoweri Museveni is apparently grooming his son, Muhoozi Kainerugaba, to be his successor, Voice of America reported Monday.
The Criminal Investigation Department last week interrogated the writers of stories in the Daily Monitor that were based on an alleged letter by the coordinator of intelligence services, Gen. David Sejusa.
In the letter, Sejusa called for an investigation into reports that orders were given to assassinate anyone who stated their opposition to Kainerugaba.
Police have shut down the offices of the newspaper and its sister radio stations after journalists refused to give up information about their sources, Voice of America reported.
"Everything is calm, but tense, very tense," said Daily Monitor reporter Tabu Butagira. "At the moment no staff is allowed to leave the premises and the police have taken over the charge of the gate and now they are at the printing press which they want to disconnect it."
Police were searching for an alleged letter by Sejusa detailing his call for an inquiry, the newspaper said.
"It is alleged by the police [the letter] was doctored by some of the media houses and that prompted an investigation," said government spokesman Fred Opolot.
