More than 3,000 prisoners are believed to have escaped the main prison in Democratic Republic of Congo.
The authorities say only around 50 prisoners got away when armed men attacked the prison on Wednesday.
A police spokesperson, Radio Okapi said that “the prisoners were dangerous and called for anyone who saw them to tell the authorities.’’
The authorities accuse supporters of Mr Ne Muanda Nsemi’s supporters of being behind the attack.
Mr Nsemi is a self-styled prophet seeking to revive the ancient Kongo kingdom and leads the Bundu dia Kongo movement.
Bundu Dia Kongo is campaigning to restore a monarchy in parts of DR Congo, Congo-Brazzaville, Angola and Gabon.
Mr Nsemi was an MP when he was arrested in Kinshasa after police accused him of inciting violence.
