In a letter to the inspector of Race Course Police station here, handed over by his lawyers, Anirudh sought grant of extension of time to appear, since he was in London, after giving a concert in Canada dedicated to the flood victims of Chennai.
Stating that he will return to India in the second week of January, Anirudh told police that he would report before them as soon as possible.
The Coimbatore Police had recently registered the case against Simbu and Anirudh following a complaint from the local unit of All India Democratic Women's Association that the song allegedly contained vulgar lyrics denigrating women.
Another case had also been registered by Chennai police against the two in connection with the song.
