Police sources said Sarojini Masih, principal of Chandigarh Baptist School in Sector 45, discovered about the theft around 2.30 p.m. when she returned home from work.

The door was bolted from inside. On pulling the door open with the help of her neighbours, she saw that the house had been ransacked and cash worth Rs 1 lakh was missing from her bedroom almirah on the ground floor of the three-storey house. Her son had left the house around noon. The thieves had apparently been keeping a watch on her house and had climbed the back wall to gain entry into the bed room, she said.
