Sixteen Central Bureau of Investigation officials raid activist Teesta Setalvad's house and office in Mumbai. The raid began early this morning.

"I don't understand rationale behind this CBI raid. The raid was conducted despite offering my full cooperation," Setalvad told NDTV.

Last week, the agency registered a case against Setalvad and her organisation for alleged violation of Foreign Contribution Regulation Act in receiving funds from abroad without taking prior permission from the home ministry.

In the first information report, the agency also named Setalvad's husband Javed Anand and Gulam Mohammed Peshimam, both directors in Sabrang Communications and Publishing based in Santacruz, Mumbai.
