After registering a case in September 2015, the CBI had

carried out searches at various places in Mumbai and registered a case against Singh in Ahmedabad.

Singh, who was then posted as Joint Director in the Enforcement Directorate, was later repatriated to his parent cadre and was currently Additional Commissioner (Customs and Excise Department) in the Northeast.

The CBI had said in the FIR that some ED officers while investigating the cases of money laundering in betting and other such activities had allegedly demanded and accepted "huge" illegal gratification from the accused and suspects.

The ED's Ahmedabad unit was probing the Rs 2,000 crore IPL betting scandal and Rs 5,000 crore money laundering case against alleged hawala operator Afroz Fatta in which the suspects allegedly sought favours from the officers, official sources said.

CBI claimed huge bribe was paid to these officers in return for favours.

After the ED Director received multiple complaints about the bribe demanded by the officers, he had forwarded those to the CBI for investigation.

The four were today produced before a court here which granted CBI their transit remand to enable it to produce them before a special court in Ahmedabad.
