P Gopalakrishna (55), who represented Ward No. 16 of the municipality, died on the spot in the attack that took place near his native Aurangabad village around 2.30 pm.
"Gopalakrishna was returning to Aurangabad after attending a function in nearby Kovvur town. When he was about to reach his village, some unidentified persons attacked him with sharp-edged weapons, in which he died on the spot," Kovvur Deputy Superintendent of Police Narra Venkateswara Rao said.
A case has been registered in this regard. Police are probing the incident and search teams have been formed to nab the accused.
"The exact number of people involved in the attack and the motive are yet to be known," Rao said, adding, "We suspect that previous enmity could be the reason behind the murder".
