At least 26 people were seriously injured, four of them critically, in an acid attack in Tripura, police said in Agartala on Sunday. One person was arrested.
Police arrested jeweller Ratan Sarkar who threw acid on a vegetable vendor and others on Saturday night in North Tripura district's Kailashahar town, 175 km from Agartala.
The jeweller had a quarrel with the vendor over the use of space in front of his shop. Following the argument, he threw nitric acid on the vendor and on the on-lookers who had gathered near the shop, a police spokesman said.
The injured were shifted to a hospital, where the condition of four was stated to be critical.
