Surat/Patna: With fresh complaints of sexual assault filed by two sisters against self-styled godman Asaram Bapu and his son Narayan Sai, the Surat Police has set up four teams to nab Narayan Sai, who has presently gone underground.

Sources said, Narayan Sai, alongwith his mother and sister, has left for Nepal, and from there he plans to leave the subcontinent.

Surat police commissioner Rakesh Asthana said, four teams have been constituted to nab Narayan Sai.

Spokespersons of Asaram ashram are tightlipped about the presence or otherwise of Narayan Sai, even as his father is presently in Jodhpur central jail..
