Due to his unemployment, his family kept taunting him and comparing him with Preeti.
Ankur's mother, who frequently visited Preeti's house, told her son that Preeti had got a job and will earn Rs. 50,000 a month.
Ankur was infuriated with daily rants and decided to end Preeti's life. Ankur's mother had told him that Preeti was going to Mumbai by Garib Rath Express.
Ankur arranged for battery acid and boarded the same train without a ticket. He kept looking for an opportunity to throw acid at her which he found when Preeti de-boarded the train at the station in Mumbai.
He tied a handkerchief on his face and approached Preeti and flung acid on her face.
