A shady subway-rider flashed a box-cutter at a fellow straphanger and then followed her around the train car as it traveled between stations, cops said Wednesday.
The 41-year-old victim was on board a southbound No. 4 train in the Bronx around 9:40 a.m. on Monday when a stranger allegedly took out his blue box-cutter and started to follow her around, police said.
She moved away from him, but he continued to trail her until the train entered the station at Jerome Ave. and East 161 St. — at which point he fled, cops added.
The woman wasn’t injured during the incident, police added.
A witness was able to snap a picture, which shows the alleged suspect wearing a dark green hoodie and blue pants.
