A diary seized from a Karimnagar lecturer, a co-accused in the case, revealed that the certificate racket is much murkier than the police initially thought. CCS additional DCP told TOI, “We have questioned the main accused, 41, from June 7 to 11. We analyzed the diary which revealed that the lecturer, in connivance with the staff of several universities in Mumbai, Kolkata, and Guntur, obtained fake certificates for the accused. At least 4,500 certificates from 60 universities across the country were obtained and sold. He had written the rates of each university certificate in the diary.
