Lameck Ntambi

Ntambi lived in exile in Nairobi and also the UFM chairman, Balaki Kirya. Prof. Lule was the President of UFM. Ntambi started befriending a Muganda girl by the names of Babirye. Naturally Museveni kept track of these men like Serumaga who had girlfriends and he used that loophole to get to then.
It seems he contacted Babirye through his NRA operatives in Nairobi and they gave her money to double cross Ntambi. One afternoon Ntambi was with Babirye at a restaurant at Koinange Street in Nairobi. He was drinking a Coca Cola. We don't know what she was drinking.
He might have stepped out to go to the toilet, we are not sure. What we know is that Babirye put poison into Ntambi's Coke. He started vomiting hours later and was rushed to Nairobi hospital, where he later died.
