Amidst demands for a ban on Bajrang Dal, the Union Home Ministry on Wednesday sought details of activities of the Hindutva organisation from all states.

In a letter to the state governments, the ministry has sought details of the action taken by them to check their activities, a Home Ministry official said.

Though there was no official word whether the Centre was contemplating a ban on the organisation, as demanded by some key UPA allies, sources said such inputs were required before declaring any organisation as outlawed.

Sources said the name of Bajrang Dal was specifically mentioned in the letter sent by the Home Ministry.

The letter comes in the backdrop of incidents of communal violence in some parts of the country leading to demands for strict action against individuals and groups involved in the attacks.

"The ministry of Home Affairs has written to state governments and sought details of the action they may have taken," the official said.

The demand for strong action against the Hindutva organisations, including Bajrang Dal, VHP and RSS have been made both inside and outside the ruling UPA, with some key coalition partners demanding a ban on these groups.
