Security operatives on Sunday evening cordoned off the offices of the leading opposition party, Forum for Democratic Change, where party leaders were meeting.
Dozens of Police officers and the military, cut off the party offices in Najjanankumbi, blocking entry and exit from the building.
At the time of the siege, former presidential candidate Col Dr Kizza Besigye was addressing party leaders from Rubaga Division.
Besigye however, was able to escape from the building and was seen waving at the officers before speeding off.
The FDC President, Patrick Amuriat Oboi also managed to exit on foot, and escaped in a commuter taxi.
Security organs seems to have been spooked by the opposition party’s “Defiance” campaign which appears to have gained momentum over the past days, with the agreed collaboration with the “People Power” Sect under MP Robert Kyagulanyi.
Last Thursday the National Security Council (NSC) headed by Minister of Internal Affairs, Gen Jeje Odongo had a meeting that was called to specifically discuss Defiance.
The NSC is made up of Ministers of Defence, Internal Affairs and Security, as well as the Chief of Defence Forces, Inspector General of Police, Commissioner General of Prisons, Director General of the Internal Security Organisation (ISO), Director General of the External Security Organisation (ESO), and the Chief of Military Intelligence.
During the Najjanankumbi meeting which was streamed live on social media, Col Besigye called on the FDC leadership to make all necessary adjustments to take power, both through the ballot, and force.
“We can go on and secure all those parliamentary seats but the real war we are fighting is to ensure that the army relinquishes power,” he said.
“The army will not cede its power just because you won a position.”
Police were yet to comment on the operation.
