Footage has emerged of the moment a pervert on a Sydney train was caught filming up women's skirts.
Samuel Tjin is believed to have regularly filmed women and girls on his commute every day to the CBD.
The 36-year-old appears to be covertly filming up women's skirts as they walk past on the platform while he sits in the bottom carriage on the train.
After a tip-off from a passenger, A Current Affair confronted Tjin on camera while outside the man's home.
