Railway Recruitment Board examinations in Allahabad were cancelled on Sunday following leakage of question papers as Uttar Pradesh Police claimed to have busted the racket with the arrest of a Railway employee and 11 others.
As many as 284 examinees, who allegedly purchased leaked question papers, were also arrested, state Additional Director General of Police (Law and Order) Brijlal told PTI.
A Travelling Ticket Examiner in the Railways identified as Bedilal, who was arrested by the Special Task Force of the UP Police in Lucknow, was the "kingpin" of the gang allegedly involved in the racket, the ADGP said.
Eleven more were arrested in Allahabad when an STF team, acting on a tip-off, raided an examination centre at Jhusi on the outskirts of city, he said.
Nine of them hailed from Bihar while two were locals, the ADGP said.
Copies of two original question papers, their 180 hand written copies, original certificates of a number of examinees and 31 mobile phones were recovered from the possession of the arrested gang members.
Examinations at all the 37 centres across Allahabad were cancelled after the leakage causing widespread resentment among the examinees who staged vociferous protests.
Nearly 50,000 candidates were to appear in the tests for 705 posts of loco-pilots.
Bedilal, a resident of Jaunpur district in Uttar Pradesh, was also arrested on February 26, 2006 on similar charges, the ADGP said.
Question papers of Railway Recruitment Board Group D examinations were allegedly recovered from his possession at that time.
STF sources said the gang used to charge a huge sum of money from examinees for providing them question papers along with answers.
Bedilal is, at present, posted in Gonda district which falls in the North-Eastern Railway zone.
