Neighbour removing the boundary stones

Respected Advocates,

I got my agriculture land measured and fixed the boundary stones by the Surveyor.But during my absence the NEIGHBOUR IS REMOVING THE BOUNDARY STONES and it is being a nuisance for me to fight with him each and every time because i am only one male head in my family but they are nearly 20 male heads in their family.What to do with this issue?How to resolve this issue?

Regards,

Surya
