Veteran sports administrator Narinder Batra's former office at the Indian Olympic Association headquarters and the Hockey India office here were on Monday raided by CBI officials who claimed to have "recovered incriminating documents and records" relating to an alleged misappropriation of funds. Batra on Monday resigned as President of International Hockey Federation (FIH) and also gave up his IOC membership, almost two months after a High Court ruling ended his reign as IOA chief.
