Investigators have discovered more than 7.5 million dollars' worth of hard cash in ousted Sudanese president Omar al-Bashir's home, prompting them to open a case into suspected corruption and money laundering, a state prosecutor employee said.

The employee, who asked not to be named, said searches would now target other members of al-Bashir's earlier leadership circles.

Investigators had found roughly 6.7 million euros (7.5 million dollars), 350,000 dollars and 5 million Sudanese pounds (105,000 dollars) during the search.

The state prosecutor employee said late Saturday that the investigations were part of efforts by military leaders to expose the corruption of al-Bashir's system. Several top politicians from the ruling National Congress Party have been arrested in recent days.

Al-Bashir - in power for 30 years - was deposed and arrested this month in a military coup that followed months of anti-government protests. Sit-ins continued on Saturday, with thousands of Sudanese protesters demanding the military hand over power to civilian rule.

The organizers behind the mass protests, the Sudanese Professionals Association (SPA), plan to present their suggestions for a government team on Sunday.
