The assailants stopped Dopura village sarpanch Parmal Singh and opened fire at him while he was on his way back to home last evening, Dholpur SP Harendra Kumar said.
Parmal died on the spot.
The preliminary investigations suggest an old dispute could be the reason behind the murder, he said.
"The family of the deceased sarpanch is in a state of shock and they are not in a position to tell us entire things, though the matter is being probed," he said.
