According to police, the two boys have been identified as Chhotu Kumar, 17, son of Vishwanath Paswan, an Assistant Sub-Inspector with the Bihar Police and Golu Kumar, 16, son of Sagar Paswan.
So far, two persons, Anil Yadav and Muni Lal, have been arrested in connection with the incident which took place yesterday while raids were on to nab others involved in the incident.
Both of them had appeared for Bihar Board's Class 10th examinations and were waiting for the results.
Other persons from the neighbourhood also joined the assaulters and kept on beating Chhotu and Golu. Both the boys tried to convince them of their innocence but the mob was unrelenting, Medhavi said.
"When the boys fell unconscious, they were loaded on an auto-rickshaw and dumped near a Tata godown along National Highway-30. Police discovered them and took them to hospital, where both of them were declared brought dead," he added.
