The girls were aged between 14 and 15 years.
As soon as the news spread, villagers gathered on the spot and alleged involvement of one police constables and four others in the incident.
The villagers also alleged that the girls were first gang-raped and then hanged from the tree.
A police constable identified as Sarvesh Yadav is absconding along with the rest of the accused, superintendent of police, city, Man Singh Chauhan said.
The villagers also alleged the police showed apathy and refused to register an FIR on Tuesday night.
Gang-rape could not be ruled out but any confirmation could be made in this regard only after postmortem, Chauhan said.
The villagers protested by blocking traffic with dead bodies on Ushait-Lilawan Road and also demanded suspension of all the policemen posted in Ushait Police station.
They also demanded a visit by the state chief minister Akhilesh Yadav to the village in this connection.
The police and administration officials have reached the spot and are talking to villagers.
