A three week stay of execution was granted last night to Benjamin Moloise, who was due to be hanged shortly after dawn today for the murder of a black security policeman... Moloise, a poet and upholsterer, aged 30, was convincted in November 1983 of the murder of Warrant Officer Phillip Selope, who was shot in an ambush in a township outside Pretoria a year earlier. The African National Congress has said it ordered the "execution" of the policeman for his part in the arrest of three ANC guerrillas who were later hanged in Pretoria, but that Moloise had no part in it.
