"They ransacked the house and decamped with Rs. 195,000 cash and jewellery worth Rs. 150,000," said a police official. House owner Ravinder Jain and son were at their jewellery shop in Nirman Vihar while daughter-in-law had gone to her relative's house.
Sudha raised the alarm after the assailants escaped. She called up her husband, who then informed the police.
The police said they are suspecting an insider's hand in the incident.
