Chandigarh, Aug 29 (IANS): Claiming that Sikhs were being shown in a bad light in the film "Son of Sardar", the All India Sikh Students Federation (AISSF) has urged the clergy to take action against actor-producer Ajay Devgn.

In a letter to Akal Takht head Gurbachan Singh, AISSF president Karnail Singh demanded action against Devgn for hurting the religious sentiments of Sikhs.

The Akal Takht is the highest temporal seat of the Sikh religion.

Karnail Singh Tuesday said the film, to be released in November, had blasphemous remarks against Sikhs.

AISSF has sought registration of a police case against the filmmakers.

"The film's trailer has demeaning dialogues," Karnail Singh said.

"In the film, the lead actor wears a Sikh turban but has the tattoo of a Hindu god on his chest. This is against Sikh principles," he said.

Karnail Singh said they had sent a legal notice to the filmmakers and asked to delete the objectionable scenes. But Devgn had not responded to the notice, he said.
