A Special Investigation Team (SIT) of Haryana Police on Sunday arrested a youth from Delhi for allegedly solving the question paper, leaked before the CBSE's All India Pre-Medical Test (AIPMT) in May this year.
The youth, identified as Gautam, wanted to become an IAS officer and was pursuing his undergraduate course in BTech from New Delhi.
"Gautam has turned out to be the main person who had solved the leaked question paper. Preliminary questioning revealed that he was preparing to appear for the civil services and his arrest is a major success for the SIT," a senior police official told Hindustan Times.
Gautam hails from Ranipur in Bihar. He, along with another accused identified as Dharmender, were arrested during raids in Delhi.
Other accused got the undergarments to hide Bluetooth devices
Dharmender, a native of Bihar's Nalanda district, is accused of getting the undergarments used to hide Bluetooth devices through which the answer keys were sent to the students appearing in the 3 May AIPMT examination, police told HT.
Besides Bluetooth devices, the police seized answer keys, mobile phone chips, micro earphones, digital watches with built-in cameras allegedly used for cheating in the pre-medical test.
A Rohtak court has sent the two youths to two-day police custody for further interrogation.
The police have arrested 22 people in connection with the leak and they are now looking for the mastermind, Roop Singh Dangi, who is on the run.
"Authorities have already been alerted to ensure that Dangi does not leave the country and his details, including passport number and photographs, (have been) made available with all offices concerned. So far, there is no input that Dangi was spotted at any of the international borders," a police source said.
Meanwhile, the police were also trying to identify the students who would have benefited from the leak. They have already identified 44 of them so far.
Nearly six lakh students had appeared in the AIPMT examination and were waiting for the result, which was to be declared on 5 June, but it was first delayed and then cancelled.
