A 45-year old BSF inspector, deputed for poll duty for the May 16 Assembly election in Kerala, was shot dead allegedly by a jawan near Kerala following an argument over leave, police said on Friday.
A search was on for jawan Havildar Umesh Prasad Singh who fled the scene after gunning down his superior Ram Gopal Meena, hailing from Rajasthan, late last night, police said.
Mr Singh had sought leave which was turned down by the Inspector following which a quarrel broke out between the two.
Suddenly, the jawan opened fire from his service rifle, fatally injuring the inspector around 11.30 pm at a higher secondary school at Kottakal, where the central security personnel drafted for poll duty are accommodated.
Mr Meena was rushed to a hospital but died on the way, police said.
A Special Investigation Team under Circle Inspector Payyoli has been formed to investigate the case, they said, adding the rifle abandoned by him at some distance away had been recovered.
