Many girls have started coming forward with their complaints against Asaram Bapu, police said without disclosing the nature of the complaint or the identity of the alleged victims.
They have also offered to help the police in its investigation.
Police, however, denied reports that it is in possession of any CD or video clippings given by Asaram Bapu's aide Shiva.
"We have not received any such CD or video clipping so far showing bapu or any of his activity. We have obtained some evidences out of interrogation of Shiva and are in the process of its verification," DCP Ajay Pal Lamba said.
Police teams have been sent to Asaram Bapu's ashram in Ahmedabad to collect evidence in the case.
Lamba said that the case is under investigation and they are yet to interrogate Shilpi, the warden at the Chhindwara Gurukul where the girl was a student and an important link in this case, as she allegedly sent the girl to Asaram Bapu.
"She is on our radar and we will arrest her at an appropriate time," he said adding Asaram Bapu's driver and cook will also be interrogated.
Police will also cross examine Shiva and Shilpi and if needed.
