Expensive homes monitored closely

In countries like India where real estate prices and corruption levels are high, people living in posh areas of a city or town will find that their homes are being monitored closely. Allegedly intelligence agency officials are closely monitoring whether a person is entering or leaving the house. These officials can detect the presence of the individual within a few hours of the person entering the house.
When these officials find that the person is not at home for some time, they will enter the home and steal low value items from the house , which the home owner will not bother to file a police complaint for. in other cases, if they find that the person is at home, they may attack the person with expensive radiation weapons causing great pain.

These officials hope to create problems for the home owners, to force them to sell the house cheaply.
