The woman, identified as Shabnam lived with her family on the first floor of an apartment. Her husband, an entrepreneur, had gone to Jaipur for some official work when the incident took place, said a police official.
The incident was reported around 7 AM when Shabnam's husband returned home and found the door unlocked. When he rushed inside, he found his wife and children - aged six and eight- lying in a pool of blood, he said.
He raised an alarm and later neighbours called the police.
