Ranjit Sinha (27 March 1953 – 16 April 2021) was an Indian police officer[4] and was the former director of the Central Bureau of Investigation (CBI).

He had earlier held positions in CBI including the post of joint director and deputy inspector general.

In addition to his main responsibility of administering the CBI, Sinha also coordinated between different anti-corruption bureaus, the Income Tax Department, and the Central Vigilance Commission (CVC) in fighting corruption.

[citation needed] He was one among four children with the eldest sister Sarojini Sinha married to 1968 batch Indian Revenue Service (IRS) officer P. K.

[1][additional citation(s) needed] He trained to be a geologist receiving a Master's in Science degree in Geology from the Patna University and later received a Master's Diploma in Public Administration.He has two brothers - Anand Sinha who worked as a senior management official with Tata Steel and the youngest Anjani Sinha.

[citation needed] In this position, he dealt with communal strife, law and order issues and crime related to international border.

[13] After having served as the heads of the Railway Protection Force and the ITBP, he was selected as the director of the Central Bureau of Investigation (CBI) in November 2012.

[citation needed] However, the Bhartiya Janata Party objected to his appointment, protesting that the Government had not followed the collegium system that it had approved and that was part of the Lokpal Bill which was waiting to be passed by the Parliament.

The original harsh report by Biswas was swapped with a toned down one authored by Sinha by the then Director CBI, Joginder Singh and submitted to the court.

[6] He admitted to the controversy, stating: First of all I completed my tenure in the RPF on 19 May 2011 and Mamata Banerjee became West Bengal chief minister on 20 May 2011.

Observing this the Supreme Court scathingly criticized the UPA government, for its meddling with the report, and the CBI, for behaving like a caged parrot that speaks in its master's voice.

On 6 May 2013, the Supreme Court asked the government to bring a law before 10 July 2013 to "insulate the CBI from external influence and intrusion".

[41] However, it was also reported that Sinha had held a grudge against Mahesh Kumar, and ordered his phone to be tapped that led to the case being busted.

[47] Sinha ordered a fresh review of all high-level appointments and high-value contracts during the tenures of railway ministers from Mamata Banerjee to Pawan Kumar Bansal.

I was made a villain by my powerful enemies in the state despite the monitoring bench of the Patna high court not even once making an adverse remark against me.

I still believe things went little overboard during the investigation in the fodder scam due to some seniors who assiduously cultivated larger than life image.
