Police in Zambia have jailed Kenneth Kaunda, the former president, five days after he returned to the country for the first time since an attempted coup.
Aides said the frail 73-year-old "father of the nation", now a vocal opposition leader, had been taken to a notorious and overcrowded remand prison, Kamwala, in the capital Lusaka after being served a police order detaining him for 28 days.
President Frederick Chiluba defeated Mr Kaunda in multiparty elections in 1991.
He imposed a state of emergency on 2 November, after a foiled coup by junior army officers who accused the government of corruption.
