The CBI has said that its Special Director Rakesh Asthana's complaint to Central Vigilance Commission against Director Alok Verma is "malicious" and "baseless". CBI said it's an attempt to intimidate officers probing his role in six cases. Asthana had filed a complaint alleging that the CBI chief was interfering in his cases, including one against RJD chief Lalu Prasad Yadav.
