In an e-mailed communication to those who stood by her and backed calls for her return to Kolkata, she said her visitors have to take permission from "higher-ups" in the government and their time and duration of meeting her is fixed by them.

Nasreen, bundled out of Kolkata in November following widespread violent protests by a Muslim group for her alleged anti-Islam writings, said those who had indulged in arson and violence had not read his book Dwikhondito .

She insisted the violence was not due to certain controversial portions of the book as no writer in the world nor she could ever be the cause of violence.

In any case, the book was first published three years ago but there had been no violence all this time, particularly even after the West Bengal withdrew a ban on it.

The author said since she had withdrawn the allegedly offending portions of Dwikhondito and there had been no protests after her action, there was no reason why she should not be allowed to return to Kolkata.

Nasreen said if important people could freely move around with security without causing law and order problem, she saw no reason why she cannot do the same.
