A sub inspector on Sunday allegedly committed suicide by shooting himself with his service revolver at a police post, a senior official said.
Sanjay Jadeja, 37, had been shifted to the Crime Branch's anti-chain snatching squad just two days earlier, Vadodara police commissioner Anupam Singh Gehlot said.
Mr Gehlot said that a diary had been recovered from the spot where Sanjay Jadeja shot himself in which the man had purportedly written that he was unable to do the work of a sub inspector.
Mr Gehlot, however, added that it was unlikely that Sanjay Jadeja killed himself because of work pressure.
Praising Jadeja as a very good officer, Mr Gehlot said that his death had saddened the entire force.
"He was the leader of the anti-chain snatching squad and was doing very good work. We are investigating what caused him to take this step," Mr Gehlot said.
