Nigeria has struck a deal to bring 50 million dollars belonging to late dictator Sani Abacha that were frozen by the Swiss authorities in 1999 back to the country, the justice department said Monday. In total, more than 600 million dollars (498 million euros) of Abacha's money has been frozen in Switzerland. Nigerian authorities finished an investigation into an individual involved in the Abacha case and, in an out-of-court settlement, secured the return of 50 million dollars through the Bank for International Settlements, the Federal Office of Justice said.
