On September 24, CBI's second-in-command Rakesh Asthana complained about interference in work against its top boss Alok Verma after the latter launched an investigation into the corruption allegation against his Asthana.
Later, Asthana wrote letters to the Cabinet Secretary and Central Vigilance Commission, listing out 10 cases of alleged corruption and irregularities against the CBI Director Alok Verma.
PM Modi summoned CBI Director Alok Verma and Special Director Rakesh Asthana.
After meeting PM Narendra Modi, Alok Verma suspended his deputy, Special Director Asthana.
In an unprecedented move, the Appointments Committee of the Cabinet sent both Verma and Asthana on leave and Verma was replaced by M Nageshwara Rao, a senior Joint Director.
Verma moved Supreme Court challenging Centre's decision of sending him on leave.
