Samajwadi Party Majdoor Sabha leader Firoj Mohammad and his neighbour Dr Naeem, a member of Lok Janshakti Party had a heated dispute over a fight between their children yesterday, according to police.
Situation turned ugly as the two politicians along with their supporters resorted to brickbatting and attacked each other with wooden sticks and iron rods, police said.
Both groups have given their complaint, and FIR would be registered after a detailed probe of the allegations, Yadav said.
