India's home secretary Anil Goswami was asked to go on Wednesday night for interfering in CBI investigations against a politician. LC Goyal, former rural development ministry secretary, has replaced him and is likely to take over soon.
The government asked Mr Goswami to resign after he admitted to making a telephone call to the CBI on behalf of Congress leader Matang Sinh, who was arrested last week in the Saradha chit fund case.
Mr Goswami was left with no choice, sources said, as he confronted an extremely unhappy Prime Minister Narendra Modi and the possibility of an unceremonious sacking before his two-year tenure was to end in July.
The new home secretary, LC Goyal, has been a joint secretary in the home ministry when the UPA was in power.
After being briefed on the controversy by Home Minister Rajnath Singh, PM Modi decided to take a tough stand in a 90-minute meeting with officials, sources said. Mr Goswami was asked to explain his actions - first to the home minister and then to the Prime Minister's Office.
Mr Goswami reportedly said he did make the call but never interfered. The explanation did not convince either the home minister or the Prime Minister.
Matang Sinh, a former junior home minister, was arrested last week in the Saradha ponzi scheme in which thousands of small investors in Bengal and Odisha were cheated out of their savings.
The CBI alleges there were large, unexplained transactions worth Rs. 30 crore between Mr Sinh and Saradha, which need investigation.
