On July 28, a defiant Pakistan said it would not arrest Saeed till adequate proof was provided of his involvement in the Mumbai carnage.

'We cannot arrest him till adequate proof is provided. There is no proof,' Pakistan's Interior Minister Rehman Malik told a private TV news channel in an interview.

Chidambaram also said his ministry had formulated its latest response to the queries submitted by Pakistan on India's third dossier on the Mumbai attacks.

'Yesterday (Friday), we finalised our response. A seven page response with attachments has been handed over to the ministry of external affairs to be transmitted to Pakistan. I believe this will be done shortly,' the home minister added.
