A Rwandan opposition activist, Venant Abayisenga, has been missing for two days.
Mr Abayisenga is a member of Dalfa-Umurinzi, a new political party formed by Victoire Ingabire who is a renowned opposition figure in Rwanda.
He was released from prison in January after a court cleared him of attempting to overthrow the government.
After his release, Mr Abayisenga went to stay at Mrs Ingabire’s house.
He was last seen on Saturday afternoon just before he left the house to buy mobile phone credit at a nearby shop.
He never came back and his phone is off, Mrs Ingabire says.
The Rwanda Investigation Bureau (RIB) hasn’t replied to the BBC’s request for a comment.
