A portion of self-styled godman Asaram Bapu’s ashram was burnt down in Pariya village at Pardi taluka here by a group of ex-followers, who are upset after allegations of sexual assault surfaced against him, police said on Tuesday.

On Monday, some people who had provided land to Asaram Bapu for building his ashram in this remote tribal area burnt down a part of the structure, they said.

They had earlier donated land to Asaram, but are no longer his supporters after the allegations of sexual assault resurfaced against him and his son Narayan Sai, they said.

Surat Police had recently registered complaints filed by two sisters — one against Asaram and another against his son Narayan Sai — of rape, sexual assault, illegal confinement and other charges.
