Ugandan police say they have charged Nigerian singers Omah Lay and Tems, as well as Tems’ manager, with “negligently doing acts likely to spread an infectious diseases” (sic).
The three Nigerian nationals have been jointly charged with four other Ugandans, according to the police.
All seven are to remain in custody until Wednesday, a statement shared on Twitter says.
Fans reacted with concern when Omah Lay, real name Stanley Omah Didia, tweeted a short while ago, “I’m in cuffs in Uganda right now with Tems”.
The pair had performed at an event in Kampala on Saturday that breached coronavirus rules, local reports say.
Omah Lay tweeted that he was “just a singer trying to entertain” and called on Nigeria’s ministry of foreign affairs to intervene.
The others in detention have not commented.
Uganda’s government has suspended social gatherings including – controversially – election campaign rallies, to limit the spread of the virus.
