Explanation:

Section 503 of the IPC defines criminal intimidation as threatening another person with any injury to his person, reputation, or property, or to the person or reputation of anyone in whom that person is interested, with intent to cause alarm to that person, or to cause him to do any act which he is not legally bound to do, or to omit to do any act which he is legally entitled to do, as the means of avoiding the execution of such threat. Threatening to burn B's house to make B desist from a civil suit perfectly fits this definition.
