Mukono Municipality Member of Parliament, Betty Nambooze, has been picked by the police on the basis of a video in which she explains how easy it is to attack Ibrahim Abiriga even with his bodyguards all around him.
Abiriga was gunned down Last Friday evening together with his bodyguard on their way home in Kawanda, Wakiso district.
The late MP was buried in his ancestral home in Rhino Camp Sub County in Arua where president Museveni was chief mouner.
Museveni promised to hunt down all those responsible for the death of Abiriga and his brother.
He also vowed to crack a whip on those using social media to instigate hatred.
