Kolkata: In a move that may lead to a political slugfest, the Bengal government has notified that the CBI will have to seek the permission of the state to investigate any matter in the state.

This comes hours after Andhra Pradesh chief minister N Chandrababu Naidu said he would not let the premier investigating agency of the country from carrying out any investigation in the state.

The CBI is governed by the Delhi Police Establish Act, 1946. According to the law, some states allow the CBI in general to investigate matters in their respective territories and, in some, the agency has to get a permission.

In Bengal, the Left Front government would give its consent to the CBI to operate independently. But now, after a high-level meeting at the state secretariat, the consent has been withdrawn.

Earlier in the day, chief minister Mamata Banerjee said while addressing a rally, "Chandrababu is right in not allowing the CBI (investigate cases in Andhra Pradesh). There are restrictions on them (the CBI) now. It wasn't there earlier. Now it has been put in place because the BJP government gives orders from the party headquarters. They have mismanaged every institution from the CBI to the RBI. It's a disaster!"

The CBI is investigating the multi-crore Saradha scam in which many from the TMC top brass are accused. The CBI is also investigating the Rose Valley scam in which two TMC leaders were arrested.
