A Special Investigation Team (SIT) of Ahmedabad police is probing the sexual assault case filed against Asaram.
The elder of the two sisters had accused Asaram of sexually assaulting her between 1997 and 2006 when she had been living in his ashram on the outskirts of Ahmedabad.
The younger one had filed a complaint against Sai, who is absconding, accusing him of repeated sexual assault between 2002 and 2005 when she was living in Surat ashram.
Asaram and his son have also moved petitions in High Court seeking quashing of the FIRs registered against them.
Arguments for quashing the FIR got over yesterday with the court reserving its order.
