He passed on at Rubaga Hospital but the exact cause of his sudden death is not yet known. He was believed to be in his late 60s.
At the time of his death, Mutumba was Resident District Commissioner, Kayunga district,a position he had held since March.
Nsereko attended the one week RDC retreat which ended on July 31 at Kyankwanzi.
Lukka Kagenyi, the deputy RDC Manafwa, said at the retreat Mutumba was in high spirits and appeared to be okay.
“I even challenged him to a run and he laughed it off,” he said.
Joshua Kasoma Zaake, the deputy RDC Gomba told The Nile Post that Mutumba death had come as a shocker days after
“I last spoke to Mutumba physically on Sunday when were setting off from Kyankwanzi. I travelled with him on the bus and he told me so many stories about his time at UMSC, about the media…it is a pity he is gone,” Zaake said.
For years, Mutumba was the face and voice of the Old Kampala Muslim faction headed by Mufti Shaban Mubaje.
He left UMSC in 2020 after his contract expired.
