I was hanging out at block 506 bedok north street 3's exercising corner just behind the bus stop when a foreign Indian worker started to eye on me and touching himself.
He followed a young female as she walked past and came back after releasing that the young lady is walking towards a brightly lit void deck with passer-bys around.
I felt uncomfortable and decided to walk away with my friends. He then decided to follow us and stand approximately 20 feet away. He furthered on with unzipping his pants and exposing himself to me.
**Ladies staying around the area should be more conscious and aware of the surrounding as he's targeting ladies that are alone**
There's an attached picture and video of his grotesque behavior. We had no choice but to stay around the area as we were waiting for the last bus.
