A 64-year-old Vancouver man was arrested on Tuesday after a 21-year-old woman came forward to say someone had followed, harassed and tried to grope her on public transit.

The Vancouver woman approached Transit Police on Monday afternoon, saying that she had allegedly been bothered over the last several months, said a news release.

The arrest came months after Global BC employee Melissa Bedford started documenting instances of sexual harassment and touching on public transit through a Twitter account, @gropedgirl.

And that was after TransLink launched a campaign last year aimed at stopping such incidents on the transit system.

It contained messages such as, “Unwanted touching is a crime. Keep your hands to yourself.”
