The government had accused Mohammed of receiving stolen property worth N100.38 billion. The money is believed to have been stolen by the late dictator when he was the Nigerian head of state from 1993 to 1998.
Several billions of Naira stolen by the military dictator and kept in foreign countries have been recovered by the federal government.
The federal government recently asked the United States to return another $500 million recently frozen by the U.S. as part of funds stolen by the late dictator.
His son, Mohammed, played a major role in the Abacha administration and is believed to have helped his father launder a lot of the stolen funds.
