CHICAGO, Ill. (CBS 2) — A Berkeley teenager has been arrested and charged with keeping a house of prostitution in suburban Hillside after a police discovered a posting advertising sex services on the Craig’s List Web site.

Kimberly Peterson, 17, of Berkeley, is being charged as an adult in the case. A second woman, 27-year-old Heidi Mudge of Minneapolis, was also arrested and charged with prostitution.

After viewing the Web site, police called the number advertised and were directed to a residence at 5710 Hawthorne Ave., which is the border street between Hillside and Berkeley.

When an undercover detective entered the residence, a woman allegedly agreed to perform a sex act on him for $300.

Gregory Potapczak, age 48, of Schererville, Ind., was also arrested and charged with solicitation of a prostitute.

All three suspects have been released on bond pending court dates in May.
