Abacha loot to be returned?

The Nigerian paper This Day (via allafrica.com) reports that money stolen by the country's late dictator Sani Abacha and hidden in Swiss bank accounts is to be returned, promised Switzerland's ambassador to Nigeria.

The repatriation of the stolen funds, some US$500 million, is not surprisingly opposed by the Abacha family. I'd be curious how they might explain how the general amassed so a huge fortune on a modest military salary.
