(CNN)The jailed vice president of Rwanda's opposition FDU-Inkingi party escaped from prison on Sunday, according to the country's correctional service.
Rwandan opposition party leader feared dead amid reports he escaped from prison
Boniface Twagirimana was missing from a routine headcount at the prison Monday, local media reported, quoting a Rwanda Correctional Service spokesperson. The spokesperson said that Twagirimana and another prisoner had managed to escape by jumping over the complex's fence and said that an investigation had been launched.
But members of the FDU -- an unregistered political party -- are calling "foul play" and fear that Twagirimana's life could be in danger.
In a statement released Monday, the FDU party questioned how Twagirimana could have escaped out of a high security prison he had been transferred to only five days prior and called on the Rwandan government for answers.
"This information...leaves us to believe that there could be foul play by Rwandan security services," the statement said.
"We call on the Rwandan government to inform the family, the party FDU-Inkingi and the general prison about the circumstances of the disappearance of Twagirimana. Mr Twagirimana was in the custody of the state which is accountable for his safety," it added.
