Police are looking for a teenage boy, naked from the waist down, who they said walked up to a Lenox Road home Tuesday night, rang the doorbell and exposed himself to the 6-year-old girl who opened the door.

The incident, about 10 p.m. Tuesday, took place when the girl answered the doorbell, thinking it was a pizza delivery. Instead, at the door was male teenager with spiked hair, pink lipstick, a red bandana and a black shirt -- and no pants or underwear, police said.

The girl's mother ran outside and saw four teens running down the street and enter a silver, two-door coupe. They headed down Pope Street toward Greenfield Street.

The girl's father returned home shortly afterward, and after searching for the car, located a silver BMW in the Kohl's parking lot. He told police that the car's four occupants ran to a house on nearby Greenfield Street.

Officers went to the house and tried to make contact, knocking on doors and windows. They said they could see people inside, but they would not answer the door.

Police have the registration for the suspects' car, and the investigation is continuing.
