Over 20 people, including three women, suffered serious burn injuries when acid was thrown during a skirmish between members of two households in Vaishali district, police said on Wednesday.
The incident took place at Daudnagar village under Vaishali police station area of the district, where children of the two households picked up a fight in the morning and complained to their family members, SHO Vinod Prasad said.
