The 26-year-old woman accused of attacking her 21-year-old neighbor with acid was undergoing treatment for depression and 'bouts of anger', according to her sister.
The accused had been in love with the neighbor's fiancé and could not accept the victim's marriage, which was fixed for April 19.
Her sister stated that she used to have uncontrollable anger episodes and had been treated for depression for over a decade.
Police revealed that the victim's wedding had been scheduled for April 19, but another woman who was allegedly in a relationship with the would-be groom threw acid on her.
The accused frequently visited the victim's house and had even had breakfast with the family on the day of the crime.
Both families had known each other for years, and the victim's sister stated that the accused asked her to apply henna on her hands before the attack.
The accused then pulled out a sipper from her bag, claiming it was an energy drink, and threw the liquid on the victim's face and body.
A case has been registered at the Gokalpuri police station under Section 124(1) of the Bharatiya Nyaya Sanhita.
