A couple and their 13-year-old son were injured after two groups of alleged Trinamul supporters clashed at Baghajatin on Saturday night.
Kalyan Mondal, wife Anita and their son Santanu were allegedly assaulted by youths after a drunken brawl between two groups at a musical soiree organised by a local club. Mondalís brother Sagar was the leader of one of the groups, police said.
While Sagar fled the house, the rivals beat up Mondal and his family. Three persons were arrested but released on bail on Sunday.
