During the investigations so far, SIT found that out of 20 employees of TSPSC who had appeared for Group-I Prelims, eight had qualified for Group-1 mains.

There have been allegations that several employees of TSPSC appeared in Group-I prelims conducted in October last year. The Commission last week cancelled Group-I Prelims and three other exams after the paper leak case came to the fore.

Nearly 2.86 lakh aspirants of Group I posts had appeared in Group-I exam conducted on October 16, 2022. Of them, 121 candidates had scored more than 100 marks. The SIT plans to question all these candidates.

The TSPSC had conducted an examination on March 5 for 833 vacancies of Assistant Engineer, Municipal Assistant Engineer, Technical Officer, and Junior Technical Officer in various engineering departments. A total of 55,000 candidates had written the exam.

However, the Commission suspected leakage of the question paper and lodged a complaint with the police.

The police on March 13 arrested nine persons including two TSPSC employees.

According to police, Rajasekhar, who worked as a network administrator in TSPSC, had copied question papers of some exams from a computer in the confidential section of the Commission and passed on the same to Praveen Kumar, who sold the papers to some aspirants.
