A senior police official said David Raju (55), posted as Station Writer at Gannavaram police station for the last one year, shot himself with a service weapon this afternoon at a private property at nearby Purushottapatnam village.
"As a Station Writer, Raju was in charge of weapons in the police station. He reported for duty as usual this morning. Shortly thereafter, he took a revolver and went out on his scooter.
"Later we received information that he was found dead," the police official said.
The head constable's family members, who rushed to the scene from his native village, told the police that Raju did not have any financial problems or family issues.
Further probe is on.
