Cops were searching for a woman who sprayed a substance on seven people in and near Manhattan subway stations on Friday.

The woman sprayed a 29-year-old man on the southbound platform inside the 125th Street station on the ­A/C/B/D lines in Harlem at around noon, according to ­authorities.

She fled from the station — but as she headed west on 125th Street, she targeted five more victims: a 47-year-old man, and four women, 48, 38, 30 and 23.

The 23 and 38-year-old victims were taken to St. Luke’s Hospital, where they were treated and released.

Then, about an hour later, she headed south to the 96th Street 1 train station, where she sprayed a 30-year-old woman waiting at the southbound platform.

Cops describe the suspect as 30, around 5-foot-6 and 200 pounds, with a dark complexion. She was last seen wearing a light blue hooded winter jacket, grey pants, black leggings and white sneakers.

Police are looking into the possibility of a hate crime because all of the victims were white and the suspect is black.
