AMU spokesman Rahat Abrar today said all these students had been studying in the University for the past one year. The alleged fraud was detected only this year following the introduction of computerised biometric techniques for verifying the authenticity of all applicants who had appeared in the entrance test conducted by AMU.
Cases of forgery have been filed against all the 20 students at the Civil Lines Police Station.
According to AMU sources, reports had been circulating for the past one year about the existence of a "well-organised" racket through which applicants were committing fraud using "impersonators" for appearing in the admission tests.
It was only in May this year that the new administration at AMU ordered an investigation into last year's admission records.
Police investigations had in May last led to the arrest of one person from Lucknow who was said to be the mastermind of this organised racket. This was in connection with malpractices in this year's admission test. The detection of fraudulent procedures in four cases in this year's admission test led to a deeper probe into last year's admissions also.
