ABIDJAN (Reuters) - Senegalese police said on Friday that they had arrested General Bora Colley, the man who ran Gambia's prisons, where human rights groups say perceived opponents were tortured and in some cases died.

Colley was made the director of prisons by Gambia's former leader, Yahya Jammeh, who lost an election last month but refused to step down. Jammeh fled into exile in Equatorial Guinea last week as a West African regional military force stood poised to remove him.
