POLICE on Monday shut down a Roman Catholic radio station that was one of the few independent sources of information in war-torn Angola, a journalists’ union said. Security forces raided Radio Ecclesia as it relayed a BBC interview with UNITA rebel chief Jonas Savimbi, arresting the director and three employees. Excerpts of the same interview were aired later on state television. Police burst into the radio station’s studios in Luanda, the Angolan capital, around 8:00pm with an arrest warrant for the director, Father Antonio Jaka, editor Laurinda Tavares, as well as a producer and a journalist, said Alvelino Miguel, a spokesman for the journalist’s union. Government officials in Luanda said they had no knowledge of any arrests. The radio was off the air as of late Monday.
