The police on 2 June arrested Bihar class 12th topper Ganesh Kumar after the Bihar School Examination Board (BSEB) cancelled his result.
A complaint was lodged against him after he failed to justify his academic abilities.
Ganesh flubbed a TV interview just like last year's topper Ruby Rai by failing to answer even basic questions about his subjects.
Board chairman Anand Kishor informed media that Ganesh, who had earlier claimed to be 24, is actually 42 and has also two children.
In an interview, Ganesh had difficulty in explaining what is 'sur', 'taal' and 'matra'.
Meanwhile, Bihar Education Minister Ashok Choudhary had extended his support to the arts topper and said he was a genuine student.
He added that even Bihar Chief Minister Nitish Kumar was happy with the results where only meritorious students passed the exam.
Ganesh secured 65 out of 70 marks in the practical examinations of Music and 18 out of 30 in the theory. He secured 92 marks out of 100 in Hindi.
Ganesh's academic prowess came into question after he failed to answer basic questions related to the subjects in which he secured the highest mark.
When he was asked to play some instruments and sing a song, he seemed unable to play anything in tune.
