The Right of Private Defence is detailed in Sections 96 to 106 of the Indian Penal Code, 1860.
Section 97 of the IPC explicitly states that every person has a right to defend:
\begin{enumerate}
His own body, and the body of any other person, against any offence affecting the human body.
The property, whether movable or immovable, of himself or of any other person, against any act which is an offence falling under the definition of theft, robbery, mischief or criminal trespass.
Therefore, the right extends to the protection of both body and property.
