A Senegalese woman television presenter was in custody on Sunday after her allegations of rape against minority Fulanis sparked protests outside her studio, her employers and police said.

Adja Astou Cisse, who works for private 7TV in the Senegalese capital Dakar, was arrested on Saturday, the sources said.

The arrest follows the May 19 murder of an adolescent following an attempted rape in Tambacounda, some 420 kilometres east of Dakar.

The former French colony has seen a string of demonstrations protesting violence against women.
