The unidentified men were reportedly trailed and apprehended while they made another delivery in the city outskirts.
Also arrested in another pair of youth who were arrested supplying tyres to rioters within the city.
This follows the arrest of an errant youth who attacked a female police officer and pummelled her with a hammer in downtown Kampala on day one of the riots.
