Mamata asks CBI probe on nun's rape

West Bengal chief minister Mamata Banerjee, under pressure over the rape of an elderly nun, yesterday said her government was handing over the case to the Central Bureau of Investigation (CBI) given the "sensitivity" of Friday's attack on the nun. She also pointed to West Bengal's close proximity to Bangladesh as a reason for the shift, amid local media speculation that the robbers may have fled across the border.
