Police later told the media that they had received intelligence through their own sources and those of the British High Commission earlier that Uganda was a ticking time bomb for yet another terror attack.
"We earlier got intelligence that terrorists were planning to attack Kampala Central District," police spokesperson Patrick Onyango told the media during the press conference, adding that some of the intelligence gathered pointed out places of worship as possible targets for the terrorists.
Police said it was not yet clear whether the suspect, identified as Kintu Ibrahim, was part of the rebel militia Allied Democratic Forces (ADF), but it had already been established through his interrogation that he had accomplices.
Uganda has had a series of terror attacks spaced out over the years. The latest terror attack on a school in Kasese left the entire country and the world in awe as over 40 people lost their lives.
Times like these require a high degree of vigilance, given that little is known about the plans of the terrorists.
While giving an address to the nation recently, President Museveni cautioned Ugandans to be more vigilant in their day-to-day lives if the fight against terror is to be won, and urged them not to panic thinking there is a big security problem.
"The planners are in Congo; we are going for them. The Congo government has allowed us, and we are going to finish all these people (the ADF rebels). My purpose in talking to you now is to make you people not panic, thinking this is a big problem. You, however, need to be vigilant in your day-to-day lives. The war on terror can be won if we are more vigilant," Museveni said.
