Besigye was arrested on Wednesday with other several opposition politicians after his supporters stoned Assistant inspector of police, Bosco Ariong, to death during his tour together with the Lord Mayor Erias Lukwagoin in the central business centre of Kampala.

According to police, over 16 people were arrested and about nine suspects are to be charged with “murder”.

However, the opposition has blamed the government force for being responsible for the death of Assistant Inspector of Police John Bosco Ariong, who was killed around Ben Kiwanuka Street in Kampala on Wednesday saying the tour of Dr Besigye and the Lord Mayor were nonviolent but it is the police who turned it violent.

Opposition leader in Parliament, Nandala Mafabi, addressing journalists, said that “it is police who have always incited violence, the activities of the oppositions are nonviolent, and we don’t attack police but is police who always attack supporters”

The Police have said that the killing of their counterpart was a lesson to them and are going to devise relevant strategies to contain marches.

Restrictions have been imposed on the movements of opposition politicians mainly Kizza Besigye who is allowed only to travel from his home in the outskirts of the capital to his city centre office under a police escort.

Dr Kizz Besigye who was a close friend and personal doctor to current president Museveni during NRM’s bush war but fell out after failing to share the National cake equally, has lost three presidential elections to Museveni consecutively.

Last year, he led popular "Walk to Work" street protests, which turn violent when his supporters clashed with police.

Wednesday's death of a policeman killed when unknown protester hit him with a rock on the head, added fuel in the burning furnace.

The Ugandan government warned that it will not allow any opposition member to carry demonstrations in the city centre.

However, speaker of Parliament Rebecca Kadaga Thursday pleaded to Activists for Change, a pressure group responsible for most of the street walks to cease their planned marches to allow parliament have a successful meeting.

According to the Speaker, Uganda is expected to hold the 126th IPU assembly which is the biggest conference ever in the history of Parliament and is meant for celebrating Uganda's Golden Jubilee.

She directly appealed to the group's coordinator MP Mathias Mpuuga to work with the organizers of the assembly in order to have a successful meeting.

The opening ceremony will be held in Munyonyo and is dedicated to the children of Uganda; President Yoweri Museveni will be the Guest of Honour.

The activities for change (A4C) this week revealed that they were to celebrate International Day against police brutality and acts as an opportunity to form and strengthen ties between groups that work directly or indirectly against state-inspired terror throughout the world where they hand over a petition to the Speaker of Parliament against police brutality.
