Uttar Pradesh Police has arrested the brother of the gang leader involved in the leakage of the All India Engineering Entrance Examination (AIEEE) question papers that affected lakhs of students.
Phool Chandra, who is posted as a clerk in the Punjab National Bank in Jaunpur, was arrested from Lucknow late last night, Senior Superintendent of Police (SSP) STF Vijay Prakash said on Tuesday.
He said Phool Chandra is the brother of the gang leader.
The arrested accused has revealed names of some persons and efforts were being made to arrest them, sources said.
Police had yesterday said that the kingpin of gang involved in the leakage of the paper was a native of Jaunpur district and has bases in Ghaziabad and Mumbai.
"The leader of the gang, which leaked AIEEE paper yesterday is a native of Jaunpur district with bases in Ghaziabad and Mumbai where he lives under pseudo names," Special Director General of Police Brij Lal had said on Monday.
He said the other members of the gang hail from Sasaram and Patna in Bihar and Ahmedabad in Gujarat.
CBSE assistant secretary Karan Singh Saini has lodged an FIR at Hazratganj police station in this connection.
"The case is being investigated by the local police, besides information about the gang is also being collected by the STF," he said.
AIEEE question papers were leaked in UP and reportedly sold for Rs 6 lakh forcing CBSE to postpone the test by over two hours and provide over 12 lakh students across the country with fresh set of questions.
The question paper recovered by the STF was similar to one prepared by the CBSE.
CBSE, which conducts the AIEEE exams, has in the meantime decided to set up a three-member enquiry committee to investigate the incident. The committee will submit its report within four weeks.
