A suicide note signed by Rajeev Sabharwal (42) stated they were committing suicide because of financial problems and no one should be held responsible. Rajeev, who had been without a job for two years, had taken some loans, but could not repay them.

Neighbours said of late Rajiv had been unable to meet the family’s expenses despite help from relatives. Some neighbours said he could not arrange the school fee and books for his son, following which he sunk into depression.

The police said they recovered celphos tablets and a suicide note in Hindi from the Sabharwals’ room.
