Hello sir!

You can file an FIR against the people threatening you. The police officer, upon receiving a complaint, may then either call the harasser and threaten them with severe consequences to stop with the threatening calls. The police can also start an investigation, taking aid from the service provider of the phone number and nab the harasser.

Section 503 of IPC, deals with criminal intimidation. It states that anyone who threatens any other person on the following grounds is liable for criminal intimidation. (i)Threatens injury to his person;(ii)Threatens injury to his reputation; (iii)Threatens injury to his property; (iv)Threatens injury to the person or reputation of anyone in whom the person is interested.

Any person charged with section 506 of the IPC will face either imprisonment extending up to 2 years or an imposition of fine or both. If the threat over a phone call was of causing grievous hurt, death, destruction to property by fire or committing a scheduled offense under IPC will invite a harsh punishment of imprisonment up to 7 years. The law is gender-neutral, and men can file a complaint against the one harassing them over a phone call as well.
