A Border Guard Bangladesh (BGB) official apparently ended his life by shooting himself with his service weapon at a camp in Shyamnagar upazila of Satkhira early on Tuesday.
The deceased was Lance Naik Parvez Alam, 30, who hailed from Noakhali and was posted at the BGB camp in Nildumur.
Other BGB members at the camp rushed the severely injured Parvez to Shyamnagar Upazila Health Complex at around 4:30am.
He died on the way to another hospital, said Nurul Islam Badal, officer-in-charge (OC) of Shyamnagar police station.
The body was handed over to BGB officials after an autopsy at Satkhira Sadar Hospital, said the OC.
Dr Ahmed Ali and Dr Tamim Hossain, physicians at Satkhira Sadar Hospital, said Parvez died due to a bullet injury on the left side of his chest.
An unnatural death case was filed in this regard, the OC added.
