I'd like to fill a complaint about Suvarnabhumi Airport and one of its employees over a sexual harassment issue. I had a flight at 2:30 am on Korean Air to Seoul at Suvarnabhumi and I was being stalked by an Airport Employee while I was using the men's airport bathroom (I am a man). The Airport employee, a young man, cannot tell if he was Thai or Burmese, followed me into the bathroom, pulled down his pants, started touching his private parts, while I was in the bathroom. I am certain that he was staring at me. And I am almost certain that he went into the bathroom because he was trying to stalk and sexually harass me. There was nobody else in the bathroom. The whole incident lasted perhaps 1-2 minutes (I did not fully realize what he was doing until I was about to leave the bathroom). This was a very unpleasant experience and I do hope that this individual will get fired by Suvarnabhumi.
