The court had on July 4 taken cognisance of the CBI's charge sheet in which the agency has alleged that Singla had demanded Rs 10 crore from Kumar for his appointment to the post of member (electrical) and it was decided between the accused that Rs five crore will be paid before the appointment and the rest will be paid after the job was done.
The first tranche of Rs 89.68 lakh was allegedly given to Singla who was apprehended in Chandigarh while accepting the money, it has said. Bansal was forced to resign from the Union Cabinet in the wake of the scandal.
