Rajasthan Technical University Vice-Chancellor RA Gupta was caught red-handed taking a bribe of Rs 5 lakh at a government guest house in Jaipur on Thursday.
Gupta reportedly demanded a bribe for increasing the number of engineering seats at a private university.
The ADG of Anti Corruption Bureau BL Soni said, "the information was shared with us on our Whatsapp helpline number. We verified the information and arranged a trap."
"The ACB team recovered a cash amount of Rs 21 lakh from the room where the Gupta was staying for the last four days," Soni added.
The ACB team is further raiding his residences in Jaipur and Kota.
The accused is about to retire from the post in July this year.
