The Punjab Police have also obtained the arrest warrants of four other MBBS students of CSMMU, who are still absconding.

Upadhyay was arrested on charges of sitting as an impostor in the Punjab medical exam that took place on June 22, 2008 in Patiala. He has told the police that he is the son of a surgeon, based in Varanasi.

Investigating the Punjab Medical Entrance Test (PMET- 2008) scam, wherein students from various parts of the country appeared as proxy candidates, the Punjab Police found that many of the impostors were from CSMMU.

They will now take Upadhyay to Punjab for further investigation, hoping that he would divulge more information about the other 10 impostors.

“It has been found that a major role has been played by some students of CSMMU, Lucknow, Maulana Azad medical college, Delhi and Government Medical College, Patna,” said LK Yadav, Commandant, Indian Reserve Batallion, Punjab.

“Gangs operating within these colleges identify medical students, convince them to appear as impostors and then also make deals for them acting as middlemen,” he said.

Upadhyay was identified by the police from the video and the photographs of the candidates that were taken during the examination in Patiala.

The picture of each candidate was taken in the examination hall and was later sent to the college for cross-checking them with the selected candidate. In many cases, the two pictures did not match.

Vice-Chancellor Saroj Chooramani Gopal said they will cooperate with the police and students found guilty will not be spared.

Following complaints about MBBS students of the university sitting as impostors for new candidates, the university had decided to hold the internal examination on the day of the UP-CPMT exam, with compulsory attendance as one of its criteria.
