Cape May County prosecutors tell The Press of Atlantic City that some but not all of the suspects consumed alcohol during the March 15 gathering in a wooded area of Lower Township.
They say the victim was treated at a hospital after being sexually assaulted and physically abused, but further details on the victim and the incident were not disclosed.
Authorities say an 18-year-old woman was charged with child endangerment and conspiracy to endanger an injured victim. The seven juveniles face charges ranging from aggravated sexual assault to child endangerment to conspiracy.
