A Delhi court on Saturday granted four days police custody of Railway Minister Pawan Kumar Bansal's nephew Vijay Singla and three others, arrested for allegedly taking a bribe to ensure the promotion of a top railway official.
Special Central Bureau of Investigation (CBI) Judge Swarana Kanta Sharma granted four days police custody "considering the nature of crime".
"Considering the nature of crime, custodial interrogation is essential to find out the source of bribe amount and also the actual beneficiary and other conspirators other than those named in FIR," the court said.
The investigating agency produced Singla, Sandeep Goyal, Dharmendra Kumar, and Vivek Kumar before the special CBI court.
Singla, a multi-millionaire businessman from Chandigarh who is Bansal's sister's son, his friend Sanjay Goyal and two others were taken by the CBI team to New Delhi for investigation.
