He rose in the ranks before being made Governor of Central Province, and in this office he played a leading role in Amin's "Keep Uganda Clean" initiative, garnering a negative reputation for his strict enforcement of the urban beautification campaign.

Following Amin's overthrow he fled to Kenya, but was extradited back to Uganda to face charges relating to the murder of the Mayor of Masaka, Francis Walugembe.

[1][9] Shortly after taking office he replaced the head of the Federation of Uganda Football Associations, despite having no legal authority to do so.

[12] As governor, Nasur played a leading role in Amin's "Keep Uganda Clean" initiative, which involved removing trash and beautifying Kampala's streets.

He appointed a committee to encourage the public to sanitise the city and oversaw a network of undercover detectives that monitored littering.

[13] Nasur also decreed a prohibition on the wearing of slippers, as Kampala residents often wore them to bathe outside or use a toilet, and he associated them with dirt.

[14] This generated allegations that Nasur's subordinates' would force people caught wearing slippers to eat them, or beat and incarcerate them.

[15] Nevertheless, he garnered a negative reputation for his strict enforcement of the cleanliness campaign and in November Amin criticised him in a military meeting, saying "it is wrong on the part of the governor who was misbehaving to the extent of flattening people's cars and beating women wearing slippers".

He then led officials in conducting "spot checks" around the city, evicting residents of unkempt houses, seizing untidy businesses, and closing down disorganised markets.

[18] Nasur believed that unmarried women increased crime and prostitution[19] and publicly suggested that they should leave urban areas and engage in agricultural production in the countryside.

In this capacity he banned the Express football club after it had defeated an army team in a game, accusing its members of subversion.

This started a war between the two countries, and in April 1979 Tanzanian troops and Ugandan rebels overthrew Amin's regime.

[26] Local authorities arrested him in Kakamega[27] and on 16 June 1979 he was extradited to Uganda and charged with the murder of the Mayor of Masaka, Francis Walugembe.

Defence lawyer Protazio Ayigihugu argued that Ntale was not present at the scene, saying it was highly unlikely he would have gone to where his father was being killed for fear of being targeted himself.

[27] He discounted Nasur's testimony as untrue[4] and concluded, "I am satisfied beyond reasonable doubt that the prosecution has proved their case against the accused and accordingly, I convict him as charged.

"[37] He remained a devout Muslim in retirement, praying frequently in the local mosque, and was a respected leader in Bombo's Nubian community.

[38] Nasur died on 18 April 2023 at Nakasero Hospital in Kampala, following an affliction with pneumonia and a decline in health related to diabetes and heart trouble.
