Two Dalit sisters, 17 and 15, were raped, murdered and then hung from a tree in Uttar Pradesh's Lakhimpur by five men, the police said today, as a village seethed with rage at the horrific crime and what they called "insensitive handling" by cops. The six arrested men include one from the victims' neighbourhood. He had allegedly introduced the girls to three others but was not at the scene of crime. "The three who carried out the crime, and two who helped them in a cover-up attempt, are from another village close to the girls'," said Superintendent of Police Sanjeev Suman.
