South African king, a nephew of the late Nelson Mandela, has been arrested after allegedly going on the rampage with an axe in the palace.
Buyelekhaya Dalindyebo, freed from jail on parole in December, broke into the Thembu royal palace in the early hours.
Witnesses said he was searching for his son, the regent, who was appointed the acting monarch while he was in prison.
The regent escaped through a window, but his wife has been injured and taken to hospital, a royal spokesman said.
King Dalindyebo was sentenced to 12 years in jail for kidnapping, assault and arson, but only served four years after the president granted some prisoners early parole last year.
He was the first monarch to be convicted of a crime in South Africa since white-minority rule ended in 1994.
The 56-year-old comes from the Thembu clan, to which Mr Mandela, South Africa’s first black president, belonged.
