Police are examining the past records of the arrested men in the sarpanch Santosh Deshmukh murder case and a related case of extortion to decide if the stringent Maharashtra Control of Organised Crime Act (MCOCA) should be invoked, sources said on Thursday. Maharashtra Chief Minister Devendra Fadnavis said he had requested senior lawyer Ujjwal Nikam to appear as a special prosecutor in the murder case. The Crime Investigation Department (CID) has sought old case papers and chargesheets against the arrested men. Deshmukh, the sarpanch of Massajog village in Beed, was abducted and brutally killed on December 9, allegedly for opposing an extortion bid by some persons who had demanded money from a windmill company. Beed Police has put up posters seeking information about whereabouts of three wanted accused in the murder case. CM Fadnavis said he spoke to BJP MLA from Beed, Suresh Dhas who demanded that Nikam be appointed as special public prosecutor in the case. Nikam was a special public prosecutor in several high-profile cases, including the 26/11 terror attacks and 1993 Mumbai bomb blasts. Congress leader Vijay Wadettiwar claimed that "smaller fish" could be killed in fake encounters to save the "big fish" involved in the Deshmukh murder and extortion cases. Leader of Opposition in the Maharashtra legislative council Ambadas Danve said the trial in the case should be conducted outside Beed district. NCP leader Dhananjay Munde, who has come under fire after the alleged involvement of his aide Karad in the extortion matter came to light, said those who murdered Santosh Deshmukh should be tried in a fast-track court and "hanged till death." The government on Wednesday set up a 10-member SIT to probe the case, headed by Deputy Inspector General -CID Basavraj Teli.
