Inspector General of Police (Law and Order) A Satish Ganesh said that around 20-25 bodies were recovered near Pariyar ghat in Safipur area of Unnao.
"During preliminary investigation, local residents informed that instead of cremating the bodies of unmarried girls they are set adrift in the Ganga river," the IG said.
He said that the bodies came on surface after water receded in the river near Pariyar ghat.
Ganesh said that prima facie the case did not seem to be related to any crime, but police were looking into the all angles.
