Kampala - Ugandan police arrested on Thursday a former prime minister who wants to challenge to President Yoweri Museveni for the ruling party's candidacy ahead of 2016 elections, while he was on his way to meet supporters at a town near Kenya's border.
In June police had banned Amama Mbabazi from holding meetings to promote his challenge against Museveni, saying their party had not yet nominated a candidate.
Andrew Felix Kawesi, Uganda Police operations commander, was shown on local television station NSB confirming the arrest to journalists in Njeru, a town 75 km outside the capital Kampala.
"I am telling you ... I am the police and I have arrested him. He has to stick to what the law requires ... there's no going to Mbale. He's now under incarceration," Kawesi said.

Mbabazi was travelling to Mbale, a town near Uganda's border with Kenya to do a consultative meeting with his supporters and promote his candidature.
Police also arrested another presidential aspirant, opposition leader Kizza Besigye, early on Thursday morning as he left his house, his aide said.
"He had just left his home this morning going to the American Embassy for a meeting with the Ambassador when police intercepted him and ordered him either to return home or be arrested," Francis Mwijukye, his aide, told Reuters.
"He refused to return home and was immediately arrested and taken to Nagalama Police Post," he said, referring to a neighbourhood outside the capital Kampala.
