The SSB jawan, identified as Gambhir Singh Gurjar (20), was found hanging from a tree near the Durga temple in the battalion campus, Sub-Divisional Police Officer (SDPO) Vikar Kumar said.
The body has been sent for post-mortem, he said, adding that a case of unnatural death has been registered at the Bathnaha police station.
The deceased SSB jawan, a native of Dayalsapur village of Madhya Pradesh's Morena district, took the extreme step apparently due to stress, the SDPO said.
Gurjar had joined service as an SSB jawan with the 24th battalion only last month, Kumar said.
