On Sunday, five workers sustained injuries when two groups of construction workers came to blows over a trivial issue in Yamalur in HAL police station limits.
Labourers hailing from different parts of north India were working at two construction sites adjoining each other and living in makeshift houses by the construction sites in Yamalur.
Two groups of workers, allegedly intoxicated, attacked each other with clubs and iron rods. A couple of them suffered head injuries, according to the police.
HAL police immediately reached the spot and bring the situation under control. Those who sustained injures have been admitted to a nearby hospital.
Eight people were arrested by the police in this connection and a case has been registered.
