"Though sad, I salute Shah Faesal IAS (now resigned). Every word of his statement is true and is an indictment of the BJP government. The world will take note of his cry of anguish and defiance," the former Finance Minister tweeted.

Faesal announced on Wednesday said he had quit the coveted service in protest against unabated killings in Jammu and Kashmir and against the marginalisation of Indian Muslims by the Hindutva forces, "reducing them to second class citizens".

After topping the civil service exam in 2010, Faesal was allotted the home cadre of Jammu and Kashmir. He served as District Magistrate, Director of School Education and Managing Director of the state-owned Power Development Corporation.

Chidambaram also referred to retired police officer Julio Ribeiro who led the Punjab Police during the insurgency.

"Not long ago, Ribeiro, the legendary police officer, said the same thing, but there was not a word of reassurance from the rulers. Such statements from our fellow citizens must make us hang our heads in regret and shame," the leader added.
