The Ugandan police on Monday closed two local newspapers and two radio stations in a bid to retrieve a sensitive letter and other documents alleging planned assignation plots of key government officials and military officers.

Judith Nabakooba, police spokesperson told reporters here that police will continue to occupy the premises of Red Pepper, a local tabloid, Daily Monitor and its sister radio stations, KFM and Dembe FM until it retrieves the letter and other documents published by the newspapers.

"Uganda police is currently searching the premises to recover the said press releases. Uganda police further requests that all the concerned parties cooperate with the police in the execution of the search warrant," said Nabakooba.

About 50 armed men stormed the Monitor Publication Company Limited at Namuwongo, a Kampala suburb at around Midday local time with a Search Warrant, blocking all exits in order to conduct the search.

The armed men disabled the printing press, computer servers and radio transmission equipment.

Another group of armed men stormed Red Pepper premises at Namanve in Uganda's central district of Wakiso for the same documents published by the newspapers.

Alex Asimwe, the Monitor Publications Ltd managing director, condemned the closure of the newspaper and the radio stations.

"The management of Monitor Publications Ltd strongly condemns the closure by Uganda Police today of its newspaper, The Monitor, and its Radio Stations, KFM and Dembe FM," Asimwe said in a statement.

"It is particularly perturbing that the police ordered our operations shut down under the pretext of carrying out a search. It is unacceptable that our business should be crippled on a dispute which should be settled in court."

The police on May 15 secured a court order compelling The Monitor Publications to hand over a copy of the letter authored by Gen. David Sejusa, coordinator of Intelligence Services to the director general of Internal Security Organization (ISO).

Daily Monitor on May 7 published a story based on an April 29 letter allegedly written by Gen. Sejusa, in which the decorated army officer asks ISO to investigate allegations that some government and military officers are targeted for assassination for opposing the so-called "Muhoozi Project".

The Muhoozi Project is seen as alleged attempts by Ugandan President's son Muhoozi Kainerugaba harboring intentions to run for the presidency after his father Yoweri Museveni.
