Devender, in an inebriated condition, threw acid on his wife Bimla and 18-year-old niece Rani last night after a heated argument over his drinking habit, police said today.
The couple stayed in the house along with their three children. Rani, who came to meet Devender and his family, suffered burn injuries in the incident.
"After the argument, Devender hurled a bottle containing acid on Bimla and when Rani tried to rescue her she was also attacked," said police.
Devender then fled from the crime scene while the victims were taken to Lal Bahadur Shastri Hospital for the treatment.
