The woman who allegedly pepper-sprayed a 68-year-old straphanger and mocked her as a “Karen” for chastising a group of fare-evaders at a Manhattan subway station has been arrested over the incident, cops said Wednesday.

Fraylee Liranzo, 26, turned herself in Tuesday — the same day the NYPD released a cellphone photo of the suspect wanted over the assault at the 66th Street-Lincoln Center station on the Upper West Side, police said.

The victim told cops she had confronted several young women for turnstile jumping at around 3 p.m. Monday when a person who wasn’t part of the group approached her on the downtown 1 Train platform.

“Mind your own business, Karen,” the woman seethed before unloading the noxious chemical, according to cops.

The victim snapped the photo allegedly showing Liranzo holding the pepper spray bottle moments before the attack, police said.

Liranzo was hit with a slew of charges, including two counts of assault, one count of assault and harassment, according to court documents.

She was awaiting arraignment in Manhattan Criminal Court Wednesday.
