With every passing day, police come across revelations as they go through the voluminous varsity records to ferret details of the racket.

One of the 11 cases registered so far has occurred after Kohchade was shifted from the revaluation department to the professional examinations section, police sources said. ``It only confirms the involvement of some more people,'' a senior police officer said.

The role of officiating registrar Prakash Badribabu Mistri has also come under doubt after the police interrogated him twice last week. The second time round, after a marathon five hours of questioning, Mistri is reported to have resorted to evasive explanations. ``Every now and then he (Mistri) says it is not my responsibility, when asked a question,'' the officer said.

Mistri can hardlyafford to look away from the goings-on, considering his more than two decade-association with the exams department. For long, he has been the Controller of Examinations.

The level of seriousness the authorities would accord examinations can be gauged from the fact that daily-wage employees were being employed for such important tasks as masking of question papers, copies and other documents. In some cases, the same employee has continued to do the job for more than 10 years, irrespective of the fact that these tasks require secrecy, police sources said.

For the crores of rupees invested in computerisation, computers were used for only printing of marklists and degree certificates with hardly any provision for data storage, sources added. Questions like these have remained unanswered during Mistri's interrogation.

In another case, a student, Varghese, managed to obtain a provisional degree certificate for Masters in Business Administration on April 26 even after his marklist was the cause of brouhaha atthe University Senate meeting on March 11, sources said. The police are surprised at how this could happen, and are now studying the Maharashtra University Act, 1994 to analyse various aspects of the scandal and the role and responsibilities of the authorities concerned.

According to an officer, the Act specifies that under special circumstances, destruction of answer-sheets, after the mandatory three-month period, can be held up. Nowhere is it binding upon the authorities to destroy answer-sheets after three months, he said.

From the scrutiny of 1997 records, the police have come across at least three marklists of engineering students where marks have been raised by as many as 25.

One of the varsity employees, Ingle, who is reportedly absconding, has been identified as a prime associate of Yadav Kohchade apart from Bunty Uike, who would scout for students desperate to shore up their marks.

Ingle's name figured in the interrogation of Kohchade's one-time confidante, Vishalaxmi. He is said to haveprocessed a couple of forged degrees for two politicians who are not from Maharashtra, police sources said.

Meanwhile, a scrutiny of the bank account held by the Controller of Exams in his official capacity is under way to ascertain the status of the funds made available to him for printing of question papers and other examination documents. A ``substantial'' Rs 68 lakh has been allotted only for printing, police said.

The scrutiny stems from speculation regarding the source of the Rs 6 lakh Kohchade used to try and bribe the then investigating officer, sub-inspector Anil Lokhande, in a city hotel on June 19.
