On 12/02/2011, at about 1815 hrs., I was sitting on the wall of the Telangkhedi lake, alongwith my friend. Another couple was sitting near us, on the same wall. Suddenly, a boy aged about 20-25 yrs., came running on the said wall. He missed me but his leg hit the other girl (the couple) and he fell, into the lake. Nothing happened to him as he knew swimming but had he hit me and had I fell into the lake, the result would have been fatal, as I do not know swimming. The security people – two from Shree Agencies- did nothing to stop the boy.
