A Massachusetts perv got more than he bargained for when he exposed himself to this badass jogger — who chased the creep down and tried to restrain him.

Aia Polanksy, 33, was seen on a video released by police running around 7:30 a.m. on July 18 in Cambridge, where she encountered another jogger who dropped his pants as she sped past him, ABC News reported.

“I went out for a run. It was 6 a.m. in the morning. I was having a great day,” Polansky said. “I was listening to fantastic audio blog — enjoying a beautiful view of Boston. I was about 3 miles from where I live. Suddenly, I saw a guy pulling down his pants.”

The single mom of three, however, refused to let the man get away with his lewd behavior.

“I just realized, this is wrong and I’m going to get this guy,” Polansky told the news station. “So I just did a quick U-turn, I was running pretty fast when he flashed his pants down. … I chased him down, I caught him and I was holding him. He did shake his hand off me the first time I caught him.”

When she caught up to the flasher, she attempted to apprehend him while flagging down others to call 911.

“I was asking people to call the police and ask for help,” she said. “Nobody did. I let my hand off him because I realized that nobody can help me out. I had to do it myself.”

Police are now searching for the suspect who escaped Polansky’s grip and was last seen running down Amesbury Street. He is described as a white male with a heavy build, short, dark hair and was wearing black and gray running gear.

“It was long enough for me to notice his brand new Apple Watch, Air Pods, the fact that he looks like a completely — the professor, teacher right next door to you and this was just … very surprising to me,” Polansky told ABC.
