Venezuela's attorney general says authorities have asked a court to order 10 more people detained in a scandal involving four banks shut down by the government due to irregularities.

Attorney General Luisa Ortega Diaz also has asked a court to bar 19 people from leaving the country in the case.

Authorities have already arrested businessman Ricardo Fernandez, who led a group of investors that recently bought the four banks Canarias, Confederado, Bolivar and ProVivienda (BanPro). He and his lawyer are charged with misappropriating deposits and providing loans to other businesses in which they were investors.

The attorney general said the lawyer's daughter, Caribay Camacho de Castro, has also been detained as an alleged accomplice.
