New Delhi: Close on the heels of Board of Control for Cricket in India's (BCCI) action against the "tainted" players, Income Tax (IT) authorities are all set to submit their appraisal reports on six cricketers this week. Highly-placed IT sources said that appraisal report on Kapil Dev, Ajay Sharma, Ajay Jadeja, Manoj Prabhakar and Nikhil Chopra would be completed this week after which these players would have to submit their block returns to the taxmen for the period of 1990-2000. The appraisal report of Navjot Singh Sidhu would also be completed by this week at the Ludhiana directorate and he would be also issued notice for submission of the block returns, the sources said, adding the report on each cricketer is voluminous running into 80 to 90 pages. The IT authorities had centralised the cases for players in Delhi and one Income Tax commissioner would be assisted by two assessing officers for speedy disposal of the cases, the sources said, adding appraisal report of bookies would be completed by next week. The Central Bureau of Investigation (CBI), meanwhile, said it would not act in haste in prosecuting the two cricketers - Mohammed Azharuddin and Ajay Sharma - under the Prevention of Corruption Act. CBI sources said they would wait for the final report of the income tax authorities before initiating any action on the two cricketers, who are public servants.
