I was slapped by a fisher woman nearby where i stay. she knows me yet she dared to slap in full view of public. she abused me a lot n I stood my ground as she was constantly shouting and abusing me for no reason when I just asked her that could i pay her the money later. she could have just refused instead she started shouting and abusing, I was startled and told her to lower her voice she threatend me and also dismantled the umbrella and charged at me with the metal rod...somehow it stuck me and i starteda recording her ..she can be seen in the video putting back the rod n the umbrella.I stood there and told her that theres no point talking to her & I stood there frozen not knowing what to do. I just put my hand ahead and requested to speak to me for i minute...the lady was shouting to others ..break her phone. I held on to my phone and bags in hands. to my dispair she landed a slap on my right cheek. i calld the police went to the ps..they made an NC..(wow i didnt know that) went to hospital .my jaw got disarranged so i go for a scan /report no fracture/but my right cheek especially the area dawn the ear was aching and there was a clicking sound as well hence had to go thru a painfull prodedure of wiring. police does not take any action so i again approach them on 17-4-18 ..fir done case gone to a lady she promises action 1. removal of the illeagal shop in lieu with nmmc whome i also contcted initially. i was on liquid diet and then soft food hence i was taking some time get myself back as this has been phyisically ...emotionally..very very tough time for me and my family. i want justice. police has just booked them on bailable terms...they r selling the fish where they wre and roaming around as if nothing happened...i feel ahast...which country m i living in.
