The probing team has arrested the student after his NEET score card, fingerprint, and photographs affirmed that he has put up the impersonator to write the exam on his behalf in Bihar.
The police had now booked the suspect under section 384 - punishment for extortion and 506(i) - criminal intimidation and the IT Act of the Indian Penal Code.
The malpractice of changing the answers had reportedly taken place in a vehicle that carried the answer sheets from Ramanathapuram to Chennai on September 1st, 2019.
TNPSC had barred the candidates who committed malpractice from appearing for its exams for their lifetime and an FIR filed against these 99 candidates and the agents under the grounds of collective plot and forging the documents.
