The Central Bureau of Investigation (CBI) on Monday raided NDTV co-founder Prannoy Roy's residence in Delhi over the alleged loan default case.
NDTV claimed that the case is a part of the probe agency's "concerted harassment" to muzzle free speech.
"Searches are being conducted today (Monday) at four places, including Delhi and Dehradun," CBI spokesperson R.K. Gaur told IANS.
The news network reacted to the incident strongly and slammed CBI's move and said, "stepped up the concerted harassment of NDTV and its promoters based on the same old endless false accusations".
"NDTV and its promoters will fight tirelessly against this witch-hunt by multiple agencies. We will not succumb to these attempts to blatantly undermine democracy and free speech in India," the statement said.
It said the news network had "one message" for those who were "trying to destroy the institutions of India and everything it stands for".
"We will fight for our country and overcome these forces."
The CBI raids come days after NDTV anchor Nidhi Razdan had an on-air verbal scuffle with BJP spokesperson Sambit Patra, after he alleged the news network was following an "agenda", during a debate over the new central notification on cow trade and slaughter. The BJP leader was told to leave the programme.
