He was being chased by one smrt staff, but the chase ended at the entrance to the station.
Really not surprising that the staff gave up the chase. Think about it, what would the staff have gotten for detaining a fare cheat
Probably more work with filling a police report & appearing in a court case.
The guy looked like a student & probably did it for fun.
I feel differently about getting involved. I have no sympathy for SMRT. It is a corporate entity out to gouge "lesser mortals"
