A Sudanese politician who had been a member of the dissolved joint civilian-military government has been arrested.
According to his relatives, Mohamed al-Faki Suleiman was picked up near his home in the capital Khartoum.
This follows the arrest of two other politicians last week.
They were part of a task force trying to dismantle the network established by the former President Omar al-Bashir. It was also trying to recover money and assets looted during his three decade rule.
Sudan is in the midst of a political and economic crisis following a coup in October which derailed a timetable towards elections.
Since the coup there have been massive demonstrations against the military.
Security forces have killed about 80 protesters.
