Pune: Four people, including a woman, were injured after a man allegedly threw an acid-like liquid at his friend following a minor dispute in Ramnagar, Yerawada, around 4pm on Friday.The four were later admitted to Sassoon General Hospital. Three of them were discharged. Yuvraj Nandre, senior inspector of Laxminagar police station, said, “We have arrested Nitin Jadhav (52), a resident of Yerawada. He is a daily-wage worker.”The injured woman, the mother of the suspect’s friend, lodged a complaint at Laxminagar police station. “Her son runs a pan stall. He and Jadhav are good friends. The two often meet and spend time together. However, the complainant’s son used to tease Jadhav, which made him unhappy,” Nandre said.“Jadhav decided to use acid to teach him a lesson. A few days ago, he visited a hardware shop and bought a toilet cleaning liquid. It is a diluted substance,” Nandre said.“On Friday afternoon, the complainant and her son were at their house in Ramnagar. Jadhav arrived outside their house carrying a bottle containing the liquid,” he said.“He abused the woman and attempted to assault her son. A scuffle broke out between the complainant’s son and Jadhav. Jadhav opened the bottle and threw the liquid at the woman and her son,” Nandre said, adding that both suffered burns to their hands and faces. At the time, a two-wheeler rider and his daughter were passing by. The liquid splashed onto them, injuring both, the officer said.
