Kathleen Kearney, 44, of Canton, Mass., was arrested about 6 p.m. Monday about two blocks from Epstein's home in the Lakeview section of Chicago, the Chicago Tribune reported.
Police said Kearney told officers she was "inviting Mr. Epstein to go to church" and that she had been watching the home Epstein shares with his wife, Marie, and young son, Jack.
Epstein identified Kearney as the person who had been warned about stalking near his home.
Kearney was charged Tuesday with two counts of felony stalking, police said.
She was to appear in court Tuesday.
