New Delhi , India ( CNN ) -- Two teenage girls , who were found hanging from a tree in northern India in May , were not raped as originally alleged , according to new forensic reports commissioned by federal investigators . The Central Bureau of Investigation ( CBI ) sent samples obtained by police in the northern Uttar Pradesh state , where the incident had happened , to a special DNA fingerprinting facility in southern India for re-examination after it took over the case , an official source told CNN Tuesday . `` ( Test ) results did n't show the girls were sexually assaulted , '' said the CBI source , who requested anonymity . `` There were also several discrepancies in the post-mortem report . '' But with the latest evidence appearing to rule out rape , investigators , for now , have dropped plans to file charges against the five . `` The CBI is not going to file the charge-sheet against them as of now . However , we are not giving them clean chit either , '' CBI spokeswoman Kanchan Prasad said . She said the investigation into the girls ' killing would continue . Under Indian law , suspects in custody for serious crimes become eligible to apply for bail if formal charges are not filed against them in the trial court within 90 days . Left hanging from tree . Five people , including two police officers , were arrested after the girls -- who were cousins aged 14 and 16 -- were left hanging from the branches of a mango tree in a remote village in Budaun district on May 27 . A photo from the village showed the body of one girl , dressed in a green tunic and pants , hanging from the tree . A large group of people , many of them young children , were gathered around the grisly scene . The girls ' families filed a complaint accusing three brothers of rape and murder . Police said an autopsy confirmed the girls had been raped and strangled . No quick fix for India 's rape crisis . Widespread anger . The case caused widespread revulsion in India and beyond , reminding people about the brutal gang-rape of a girl on a public bus in Delhi in December 2012 . Back then , a 23-year-old physiotherapy student was traveling home from a movie with a male friend when at least five other men on the bus dragged her to the back of the bus and then beat up her friend . The men took turns raping the woman as the bus drove around the city for almost an hour , police said at the time . The two friends were then dumped by the side of the road , with the young woman later dying from her injuries . That incident energized activists and women generally , with government officials promising action to ensure that girls and women feel safe . Rape order on child brings scrutiny on India 's village councils . The girl whose rape changed a country .
