The incident came to light this evening when the bodies of Sadhna and her two children -- five-year-old son and three-year-old daughter -- were spotted hanging from a ceiling fan by a neighbour around 7 pm who then informed the police, the woman's husband and other family members.
The victim's family has revealed that the woman was suffering from depression.
The police recovered a suicide note in which the woman said that she was responsible for the extreme step.
"However, the exact cause behind the extreme step is not mentioned in the note," a police official said.
The woman's husband, who is a taxi driver, was not at home when the incident took place. The couple got married eight years back.
