After reading your query, I would like you to know that purposely touching or applying force on other persons or things related to the person without his consent with the intention to harm the person is known as a battery. So, a complaint of battery can be filed in the present case,
There are two defences available to you.
1. Self Defence
Self-Defense is the most common defense which is used in assault and battery cases. It means to protect yourself from unlawful force implied by other people. In this defense, it is to be proved that the defendant was safeguarding himself from the unlawful force of the complainant. But in this case, the defendant must prove that he did not provoke the other person and there was absolutely no other way to save himself.
Essentials of self-defense are:
- The threat of unlawful for or damages.
- Reasonable fear of harm.
- No provocation by the accused.
- No other way to save himself
2. Defense of others
This defense is similar to self-defense, as in this defense the defendant is trying to save another individual, not himself. In this defense, there must be an honest and reasonable fear of harm to another person.
This defence is more applicable in this case.
Hope this helps
