In a late evening co-ordinated operation in Gandhinagar, CBI arrested C S Bharti, a 1994-batch Indian Revenue Services official, agency sources said here.
They said Bharti had allegedly demanded Rs 30 lakh from a constructions company - Drishti Constructions - to help it in scrutiny and assessment of its Income Tax returns.
After getting the input, the agency laid a trap, during which it was found that delivery of the bribe money was allegedly given to a third party which was arranged by a middleman on the instructions of Bharti.
