Transit Police report arresting Yoa Wong, 27, of Quincy, on charges he used his phone to photograph up a woman's skirt on the escalator at the Broadway Red Line stop yesterday evening.
Wong was so intent on getting a good shot between the women's legs on the up escalator around 7:45 p.m. that he bumped into another man while positioning himself. The man noticed what Wong was up to and:
The witness followed Wong out onto Dorchester Avenue and was able to have someone contact 911 and prevent Wong from leaving until police arrived.
Wong was charged with upskirting, police say.
