This is Sridhar Reddy Dyava my father Prathap Reddy Dyava and Uncle Polepelly Satyanarayana reddy have purchased 2 plots of each 320 sqyards in survey number 682, Narayana Swamy Nagar, Peddapalli in the year 2003 (Document numbers: 997/2003 and 999/2003) from Kommu Jagan, Vaidya Ramesh and Goli Anji Reddy. Recently 1 month ago in our land local broker Krishna with the support of political people (Ex-Sarpanch of Appannapet Satyanarayana Reddy and others) have put hut so we visited our land and removed Illegal hut on 3-July-2021. after that our Uncle is receiving continuous threating phone calls from krishna to sell our land for some low price otherwise he will dig the land, put basement and sell it to others through some fake registration document (2005). we ignored his words as we are the actual legal owners of our plot from last 19 years. again yesterday to threaten us Kirishna and others digged 4 corners of our 2 plots to plan for some illegal construction activity so request you to look in to this matter on priority to protect our land.
