"It seems the candidate indulged in cheating by smuggling in a camera at the examination centre," the source said.
The candidate has already been identified and his results have been withheld by the institute, he added. However, he declined to divulge any more details about the candidate or the centre.

On May 31, Mr. Anand Rai, who exposed the Vyapam scam in Madhya Pradesh, had alleged that the question papers of this year's entrance exam for MBBS course of the AIIMS were leaked.
Following this, the institute constituted the committee to probe how snapshots of the test came out in public.

He claimed to have received the question paper screenshots from a source who said these were leaked from a college in Lucknow when the online test was on.
