I shall be obliged if you could kindly let me know as to what is action to be taken. Also, the above said person has encroached in my land i.e. acquired the space in front of House, Space west side of the House & in Distribution letter there is no provision for way to go to house and come back as in another land he has acquired the space for putting the waste of animals etc. This is all above said illegal activities by the said guy.
