Immediately lodge a complaint with Police and register a FIR u/s 384, 509 IPC.

There must be a reason behind this threat and try to find this out.

Inform the elders of the locality so this incident may not be repeated when you leave for your duty.

1. As per the information mentioned in the present  query, makes it clear that your and your family hasve been threatened by some gundas at your neighbour hood.
2. Sir, there is a law to get the FIR registered against them.
3. But, as you said that you don’t want to go long for the legal procedure, then there is a way to get protection from the Hon’ble High Court, though Hon’ble Hogh Court would also direct you to take lower legal remedy if approaching magistrate and get the FIR registees and get the protection.
4. And once you get the protection then the matter would go for the mediation for sure where they can apologise and give undertaking to not to repeat the acts of offences.

1. You have to file the FIR first. UNless FIR is filed any proceeding before any court of law to seek protection will be an exercise in futility.

2. File the FIR and then you may file a protection petition before the High Court to secure the life and liberty of yourself and family members.

You can send a letter to the superintendent of police through your commandant  mentioning  the  prevailing  danger to  your parents and seek protection .

This is the next best option.

Dear Sir,

How to File a Harassment Complaint Against a Neighbour

Yes, calling a police if your neighbor harasses you is an option to go with. You have the option to call the police by just dialing the police number 100 and police will come to the place mentioned by you in the phone call. They will come to the spot and ask you the problem and then will take the action against them. And, when they will reach the spot you should be having sufficient proof to prove the harassment by neighbors.

Harassment Through Nuisance

You may be living in an apartment or in a duplex, often it happens, when you hear loud music sound from the neighbor’s house, you try to ignore that sound for as long as possible but sometimes, such noise may make life difficult. This type of nuisance is defined in Section 268 of the Indian Penal Act.

Section 268 of the Indian Penal Code defines nuisance when the person is guilty of a public nuisance when he does any act which causes injury, danger or annoyance to the public or the people in general who live or occupy the property in the neighborhood.

A common nuisance is not excused on the ground that it causes some convenience or advantage.

If this type of harassment is faced by you from your neighbor then, you can file an application under Section 268 of IPC in the court of magistrate.

Punishment of nuisance is defined in Section 290 of IPC, which is mere Rs. 200 but the court can do much more.

As a matter of fact, calling 100 is most effective as, after a visit or two from the police, such nuisance is likely to stop. In extreme cases, police may even confiscate the instruments that are used to cause nuisance like – loudspeakers or sound boxes, or drones, cameras or such other tools.

Sometimes, police does not intervene despite laws being there as they do not like extra work on their plate or because the other party is very influential. In such cases, you may need to take help of legal experts. Harassment Through Mischief

When you live in a duplex, you are sharing a common wall. If your neighbor starts construction in that common wall you do not have the right to stop him from constructing because it is his legal right but if during the construction work your property gets damaged, you can ask him to compensate for the loss suffered by you but if your neighbor refuses to pay you the amount then you can file a case under –

Section 425 of IPC which states that whoever with intent to cause, or knowing that he is likely to cause, wrongful loss or damage to the public or to any person, causes the destruction of any property, or any such change in any property or in the situation thereof as destroys or diminishes its value or utility, or affects it injuriously, commits mischief.

You can file suit for declaration and mandatory injunction in a civil court as well.

You can claim damages in the same suit.
