"We have learnt of instances in which volunteers of some Ganeshotsav mandals have misbehaved with women devotees. Mumbai police will serve a notice to them asking them to explain," a grim Patil told the media.

The warning came after volunteers at the famous Lalbaugcha Raja Sarvajanik Ganeshotsav Mandal in Parel pushed and dragged many women, in some cases by their hair, during the ongoing 10-day festival.
