A special prosecutor says a panel of judges will take up the case against the son of Senegal's former president.

Karim Wade, whose father left office last year, has been accused of misappropriating state funds.

He is being asked to explain how he managed to amass a personal fortunate of more than $1.3 billion. Wade's lawyers have vigorously denied the allegations of wrongdoing.

Authorities brought Wade and several of his associates into police custody Monday for questioning and they spent the night there.

Special prosecutor Alioune Ndao said the judges will start looking at the case Wednesday.

Senegalese had called Karim Wade the "Minister of the Sky and of the Earth" after his father handed him a "super ministry" with responsibility for international relations, development, infrastructure and air transport.
