A BSF constable on Thursday allegedly shot himself dead with his service rifle in Koteshwar town of Lakhpat taluka in Kutch, BSF officials said.
Constable GM Reddy posted at Koteshwar shot himself in his head and died on the spot, BSF IG AK Sinha said.
Reddy had joined duty a day before yesterday after returning from a two-month leave, he said.
Sinha said the reason behind the young constable's action was yet to be known.
The 25-year-old constable was posted with the 117 Battalion of the BSF at Koteshwar which is the last land point of India.
Beyond Koteshwar is the creek region, a huge marshy area, many times used by Pakistani fishermen to infiltrate into Indian territory.
Last month, a CISF jawan who was under severe debt and family problems had fired indiscriminately in Naroda area of the city and injured five persons, including a policemen.
He was later arrested and disciplinary action was ordered against him.
