The report said Namrata Damor, whose body was found near railway tracks in Ujjain district on January 7, 2012, had died a "homicidal" death caused by "violent axphyxia as a result of smothering".
The development came a day after an embattled Chief Minister Shivraj Singh Chouhan recommended a CBI probe into the scandal that is said to have claimed 45 lives.
"We have ordered a review of the death of Namrata Damor. Sub-Divisional Officer of Police (SDOP), Tarana, R K Sharma will reopen the case," Ujjain Superintendent of Police Manohar Singh Varma told PTI today.
Police had registered a murder case following her death but later closed it describing it as an "accident".
Despite Chouhan requesting the Madhya Pradesh High Court yesterday for a CBI probe into the scandal that has dented the credibility of his government, there was no let up in Congress' relentless assault on him with the party slamming the "criminal delay" in ordering an investigation by the central agency.
