The suspect, identified by authorities as 41-year-old Christopher Pagano, was arrested at his Norristown home Thursday.
Investigators suspect Pagano is the man who reportedly drove up to women on several occasions and offered them money to put cheese on his genitals and perform a lewd act.
The story went viral after a Philadelphia neighborhood town watch group posted a blurry cellphone picture on its Facebook page of a half-naked man in his car holding up what appears to be cheese.
The group dubbed him the "Swiss Cheese Pervert."
Pagano is expected to face charges of indecent exposure, stalking and harassment. He's in custody and it's unclear if he has an attorney.
