Pradhan Ramji Tewari, his two sons and a nephew yesterday barged into the house of Tribhuvan Tewari (80) and his wife Dharma Devi (78) in search of the couple's son, police station incharge of Chauri, OP Rai said.
Pradhan and the couple's son had slipped into a dispute when the latter objected to pradhan's tractor passing through his field, saying that "it was neither a road nor the land of gram samaj", he said.
A hunt has been launched to nab Pradhan and his family members who are absconding since the incident took place, Rai said.
