The case comes close on the heels of self-styled godman Asaram Bapu allegedly raping a 16-year-old girl.
Mahendra Giri alias Tunnu Baba was arrested yesterday after police raided his ashram at Neelkhand village in the district and rescued the woman.
The victim's husband and mother-in-law also lived in the ashram and they allegedly assisted Giri in the crime, police said, adding that both of them were also arrested.
A case has been registered against Giri under sections related to rape, wrongful confinement and criminal intimidation of the Indian Penal Code, police added.
