Kibirango according to Uganda Law Society (ULS) succumbed to injuries he sustained during the October 14 attack in Mutungo, Nakawa Division, in Kampala.
Kibirango woes started on Monday this week when he went to a mobile money shop in Mutungo, Nakawa Division, in Kampala and reportedly left with a phone he found at the counter by mistake.
Deputy Kampala Metropolitan police spokesman, Luke Owoyesigyire said following Kibirango's death, the case file has now changed from attempted murder to murder. Sgt Twijukye who is attached to Nakasongola military school was on Thursday night arrested by Flying Squad Unit in connection to Kibarango's attack.
"He is dead. It is now murder. Unfortunately, all others (suspects) are still on the run," said Owoyesigyire.
Police on Thursday said that Kibirango went to a mobile money shop holding a charger and a phone in his hands. Owoyesigyire said that at the mobile money shop's counter was another phone belonging to Sgt Twijukye.
Kibirango reportedly placed his phone on top of Twijukye's phone and after making mobile money transactions, he unknowingly picked both phones.
The deceased had just walked for about 100 meters when Sgt Twijukye noticed that his phone was missing. Twijukye and the mobile money operator only known as Ivan confronted Kibirango accusing him of stealing his phone.
Kibirango denied stealing a phone saying he had only picked his and charger he came with. Kibirango asked Sgt Twijukye and Ivan to go with him to Mutungo police station which was a few meters ahead.
But before they could reach Mutungo police station, Sgt Twijukye allegedly spotted the phone in Kibirango's pocket phone and at that moment Kibirango was subjected to endless slaps and kicks.
His pleas for innocence and apologies fell on deaf ears. The growing mob was joined by boda boda riders and the beating continued. By the time Mutungo police arrived, Kibirango had been beaten to a pulp. He was rushed to the hospital and a hunt for his attackers started.
