Three people thought to be South Africans have been arrested in Zimbabwe, the department of foreign affairs said on Wednesday.
The three were being held on charges of immigration violation, foreign affairs spokesperson Ronnie Mamoepa said in a statement. "The South African embassy, in Harare, is in urgent engagement with the Zimbabwean authorities on this matter," he said.
"Consular assistance shall be rendered according to standing procedures." The arrests follow the jailing of South Africans Bernet Hasani, Resemate Chauke and Simon Maodi for six months each on Monday.
A court in Zimbabwe convicted them of possessing broadcast equipment without authorisation, in breach of the country's media laws, according to a state newspaper.
The three were found in possession of equipment bearing the logo of Britain's Sky News channel when they were pulled over at a roadblock last week. Sky intends appealing on their behalf.
