Consider Assistant Commissioner of Police of the Metropolis, the third highest rank in the Metropolitan Police Service of London, UK, ''i.e.'' covering a population a bit less than half that of Sri Lanka. Most of the people in that role are notable, so, by extension, it seems likely to me that holders of the third highest rank in the Sri Lanka Police Service would probably be notable. The current article clearly fails  as is, but there is material out there, like https://www.highbeam.com/doc/1G1-270553665.html, http://archives.dailynews.lk/2011/10/24/news60.asp, http://archives.dailynews.lk/2011/10/26/spo08.asp, and passing mentions in http://www.sundaytimes.lk/000130/splusm.html and http://archive.srilankamirror.com/sports/11965-nishantha-and-vajira-spend-4-lakhs-on-obituary-notice. So, on balance, I'd go with keep
