A 6-year-old girl was repeatedly raped over the summer by five other youngsters ages 8 to 14 who "knew what they were doing," police said.
The girl was visiting the area and was friends with at least one of the children, police said. She eventually told relatives of the attacks.
Four boys -- ages 8, 11, 13, and 14 -- and a 12-year-old girl were arrested and all pleaded innocent last week in Juvenile Court to delinquency.
"The children did know the gravity of the situation. They knew what they were doing," Sgt. Dave Van Pelt said. "This was not a childhood prank. We are treating this as a sexual assault."
The children were released to the custody of their parents under home arrest. Pretrial conferences are to begin next month.
