The film crew member, whose name police refused to reveal, was arrested on Wednesday and a case was registered against him after locals objected to a scene in which a man dressed as Lord Shiva was pulling a rickshaw in which two burqa-clad women were sitting.
"A case under section 295 A (injuring or defiling place of worship with intent to insult the religious of any class) and 153A (promoting enmity between different groups on ground of religion, race, place of birth, residence, language) of Indian Penal Code (IPC) was registered against the unit director and the three actors at Kotwali police station," said a police official.
The unit members were shooting the scene in Chandni Chowk area on Wednesday.
Initially, people thought the actors were members of a Ram Leela party but on seeing cameras, they inquired about the issue.
The actors told police that it was a dream sequence of the movie and they had all the legal documents and permission for shooting.
But a mob that gathered at the police station started shouting slogans that the film-makers were hurting religious sentiments, forcing police to take action.
The officer said that no case has been registered against Aamir Khan.
