On Wednesday, Rahul Kumar, the third-topper from Science stream, was arrested from Vaishali district by Special Investigation Team (SIT) in links to the Bihar toppers scam.
Rahul was a student of the infamous, Vishnu Rai College and had secured a third rank in the class 12 Bihar School Examination Board (BSEB) examination.
After the scam came into light, Kumar was asked to appear for a retest. He failed the retest which led to his initial result being cancelled by the BSEB.
A total of 14 students had been called for a retest by the BSEB after a news channel broadcast a sting in which Rubi Rai, the Humanities topper said: “Prodikal (read political) science is about cooking”, and Saurabh Shreshtha, a Science topper, said: “Most reactive element in the periodic table is aluminium”.
The sting suggested that the toppers might have used cheating and fraud to achieve the top ranks.
Ruby Rai and Saurabh Shreshtha were also students of Vishnu Rai College.
The SIT of Bihar Police then lodged an FIR against Rahul, Ruby, Saurabh and one other such topper.
The V.R. college director-cum-principal Bachcha Rai was arrested in June in connection with the incident and was lodged in Beur jail in Patna.
At least 20 people have so far been arrested in connection with the scam.
