Police are looking for a subway rider accused of "forcibly rubb[ing] himself against" a woman's backside last week. The victim said, "I tried inching away and repositioning myself so our bodies weren't touching, but it kept happening. I also quickly realized he was physically aroused, and that the movements he was making were not accidental."

The rider, Kelsey Miller, says she got on an L train at Bedford Avenue around 9:15 a.m. last Wednesday, July 12. As the train headed towards Manhattan, she felt someone grinding against her in an "aggressive" manner.

"I first assumed it was due to the crowd and the movement of the train," she said. After determining that he was deliberately rubbing against her, Miller said, "At one point, I even looked over my shoulder and was able to see his pelvis moving."

"I continued trying to move away, I looked at him directly, to let him know I knew what he was doing," she recalled. "He stopped for a few seconds then started again. Then I kind of hip-checked him, trying to shove him off, and again he stopped doing it for a few seconds then started again. That's when it occurred to me to take his picture."

Miller took photographs before the train stopped at First Avenue. "He didn't react at all in the moment, but when we stopped, he said, 'Excuse me, excuse me,' as if he were trying to exit the train through the doors on the other side of the car. Someone near the open doors even said, 'Someone's trying to get off the train,' so that the crowd would move. But he didn't exit the train. He stopped in the middle and held the pole. The same person said, 'Oh, you're not getting off the train?' It was clear to me that he was just trying to get away from me because I took his photo," she said.

At Union Square, Miller exited the train and reported the incident at the transit police station there. Officers then contacted the Transit Special Victims Squad. "Two detectives from that unit came and picked me up and brought me to their office. They interviewed me and I filed another report with them," she said.

She also told DNAinfo, "Don’t question yourself. This is not something that's an icky-but-normal part of being a women in the world. It's a crime and will be treated as such."

Police are now asking for the public's help in locating the suspect, who is wanted for forcible touching. He is described as being about 5'6" with brown eyes and black hair. He was last seen wearing an orange t-shirt. Anyone with information in regards to this incident is asked to call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782). The public can also submit their tips by logging onto the Crime Stoppers website at WWW.NYPDCRIMESTOPPERS.COM or by texting their tips to 274637 (CRIMES) then enter TIP577.

Subway sex crimes are up 52% in the past three years, an increase that may be partially attributed to an option on the MTA's website, introduced in 2014, that allows riders to report incidents. If you see or experience sexual misconduct in the subway (this includes seeing a masturbator, being groped, being grinded on, etc.), you can report it to the MTA and police on this website. There's also a place for you to upload photos and/or video. Don't let the perverts win.
