Two head constables, C B Maruti and S S Singh, were injured in the incident and were admitted to a hospital here, they said.
Sanjay, they said, was overpowered by other men present in the camp and taken into custody, they said.
Local police was investigating the case even as the paramilitary force has ordered a Court of Inquiry (CoI) into the incident, they said.
The Ettapalli camp of the Central Reserve Police Force houses a unit of its 119th battalions that is deployed in the area to conduct anti-Maoist operations.
