Can Police arrest a person without warrant ?

Our Indian constitution provide some fundamental rights to every citizen of India. Which are like right to freedom, right to speech, right against exploitation etc. Because of these fundamental rights a person can go freely anywhere, he could live the way as he want, and he can adopt any religion. But when constitution give rights there are also some duties which a person has to perform like he can not break the law, he can not harm any other person. There is a famous maxim

"Treat others how you want to be treated"

This is the golden rule to live in a healthy and safe society. But if someone breaks law there is a need to take an action against him. So the person has to be arrested and law dispossesses his liberty.

Arrest:- Meaning of "arrest is to put a person in custody in charge of commit a crime and to restrain his liberty by legal authority".

There are mostly two types of arrest 

• Arrest with warrant
• Arrest without a warrant
