Hyderabad, March 7 :    Hyderabad, March 7:  The Andhra Pradesh government has agreed to order a CBI inquiry into the circumstances leading to the death of actress Pratyusha last month. Chief minister N. Chandrababu Naidu told the Assembly he was ready for either a judicial probe or a CBI inquiry into the controversial incident in which relatives of Telugu Desam and Congress leaders are allegedly involved. Police and doctors have given conflicting versions of the death. While the city police commissioner termed the death a 'murder', the DGP said it was a 'suicide'. The doctor who conducted the post-mortem, Muniswamy, alleged that DNA and semen samples were tampered with at the forensic department. Pratyusha and boyfriend Siddhartha Reddy drank coke laced with pesticide after their families blocked their marriage. Siddhartha, however, survived. Siddhartha issued a statement saying Pratyusha died due to a 'higher dosage' of pesticide. He confessed that some relatives of ministers alleged to have gangraped Pratyusha were his 'close friends'.
