One of Mexico's most famous pop singers, Gloria Trevi -- who went into hiding a year ago following allegations she was involved in child sex abuse -- has been arrested in Brazil.

The Mexican authorities said Miss Trevi and her manager, Sergio Andrade, who's also accused of abusing girls in their care, were detained by Brazilian police in Rio de Janeiro.

Miss Trevi, has repeatedly denied any wrongdoing.

In November, the Mexican authorities issued an arrest warrant for her and Mr Andrade.

The singer rose to fame throughout Latin America in the late 1980s with what correspondents describe as a sexually flamboyant and politically rebellious image.
