Mohammed Ibrahim Suleiman, arrested Wednesday, is the latest senior member of the regime of ousted President Hosni Mubarak to be taken into custody. The officials are being investigated on corruption-related charges, with many allegedly using their positions within the government to broker sweetheart deals.

Suleiman served as a minister of housing from 1993 until 2006. Critics say that during this period, state-owned lands were sold at cut-rate prices to businessmen close to the ruling party.

Suleiman’s successor, Ahmed Maghrabi, is also being investigated.
