A doctor from Indore who was a suspect in the all-India post-graduate entrance exams fraud which took place in the city earlier this month has been given a clean chit by the police. The crime branch confirmed that the doctor, who had introduced the two arrested city-based doctors to Mohit Chaudhry, the kingpin of the fraud, had no malafide intentions and was innocent.

"Our investigations have revealed that the doctor, who originally belongs to Ujjain, did not have any idea about the intentions of the three accused - the two doctors and Chaudhry. His actions were that of a friend who tried to offer help when contacted,'' claimed a senior police officer.

Police sources said that upon investigating the bank accounts of main accused Chaudhry they found deposits of only Rs 2 lakh. "We have found that the accused accepted only cash from the doctors who were candidates in the medical entrance exam. We are raiding a couple of places in Madhya Pradesh and in NCR to recover the money Chaudhry charged from the candidates.

A senior investigator added that Chaudhry charged money from students by promising to get them "pass marks" in term exams of their colleges. "He charged between Rs 2,000-Rs 10,000 from each student. Most of these students passed on their own merit though. Chaudhry would claim that they have passed because of him while he returned the money to those who had failed. This led to him earning a lot of goodwill in the student community,'' said the source.

Meanwhile, raids are on to nab the other doctors who took Chaudhry's help in the January 8 entrance test. "We have important leads on the whereabouts of these doctors and are working to nab them,'' said the senior officer.

However, cops also fear that some crucial evidence might also be destroyed with both doctors claiming they have disposed of the special shirts that came fitted with the Bluetooth device, the earphones and the SIM card that was used by the doctors to stay in touch with the gang.

"We know that the accused duo had brought the mobile phones from a shop in Connaught Place. We are interrogating the duo and trying to find out in which area the accused had disposed of these items. Since only a couple of days have passed, we are hoping to recover the items.

Authorities at AIIMS claim that the police had initially visited the Noida exam centre immediately after the arrests on exam day to verify whether the question papers recovered from the accused were genuine. "We had visited AIIMS first and met with the examination controller's officials to check the authenticity of the question paper,'' said an officer.

Ravi, a first year student of Rohtak's PGI Medical College, and a resident of Palwal,

and an alleged kingpin in the gang along with Chaudhry, might have roped in his own set of doctors, said police sources. "This revelation also means that the number of aspirants in touch with the gang automatically go up. We can get further inputs on this only after we arrest Ravi,'' said the source. Crime branch sources had earlier said that 11 doctors are under the scanner.
