Ugandan reggae star Robert Kyagulanyi - better known as Bobi Wine - has been arrested, local media are reporting including the government owned New Vision and the privately owned Monitor.
He is campaigning as an independent for a hotly contested vacant seat outside Kampala in a by-election that is due to take place on Thursday.
Both papers say no reason has been given for his arrest. Though the Monitor reports that his supporters clashed with a rival candidate's supporters yesterday.
President Museveni of the NRM and his long time rival Dr Kizza Besigye (FDC) are also due to hold rallies there today to back their party candidates.
Local TV stations have posted videos and pictures of the arrest on social media.
