BHOPAL: In another big embarrassment for the state government, another former exam controller of Madhya Pradesh Professional Examination Board (MPPEB) ? Sudhir Singh Bhadoria ? has been booked in connection with the multi-layered examination and recruitment scam.

Bhadoria had a longer stint in MPPEB than his successor, Pankaj Trivedi, who was arrested in September 2013 in connection with irregularities in PMT. During interrogation his involvement in several other entrance and recruitment exams conducted by MPPEB came to light. Bhadoria was MPPEB's exam controller since 2006. He was replaced by Trivedi in 2011.

Insiders say an in-depth investigation into Bhadoria's tenure will open a Pandora's Box, including a scam in Pre-Engineering tests (PET) which is out of STF's ambit. He has been named in the FIR on basis of statement given by Deepak Yadav, another scamster, arrested by Gwalior police on Thursday.

Bhadoria's modus operandi was similar to that of Pankaj Trivedi. "Select candidates were advised to leave their answer sheets (OMR sheets) blank and were given high marks after exam," said a police officer. Answer-sheets too were leaked prior to the exam date, he said. There are also demands for a probe into results of Bhadoria's daughter who had topped the PET exams.

Bhadoria, who is presently holding charge of director at Shri Govindram Seksaria Institute of Technology and Science (SGSITS) Indore, was booked along with seven others.

The special Investigation team (STF) investigating MPPEB scam at Gwalior had lodged FIRs against eight people ? Sudhir Singh Bhadoria, his successor Pankaj Trivedi, Sahay's son-in-law B R Srivastava, Gulab Singh Kirar's son Shakti Singh, ASI Veer Bhahdoor Singh Bhadioria, Vishal Yadav and Rashmi Parihar.

Gulab Singh Kirar, a relative of chief minister Shivraj Singh Chouhan, has submitted a memorandum to police requesting that his son should be arrested only after an inquiry.

Police said all eight have been booked on the statement of kingpin Deepak Yadav, who was arrested by Gwalior STF for his alleged role in rigging examinations since 2006. He was picked up late on Tuesday.

A resident of Gwalior, Yadav is accused of using unfair means to help over 100 candidates clear exams for postgraduate medical courses. Yadav's name surfaced during interrogations of several candidates who paid bribes to get admission. Police officials claim he will be questioned for his alleged role in PMT and Pre-PG entrance exams conducted since 2006. Yadav was part of the racket much before Indore's Jagdish Sagar and his gang, it's alleged.
