10 middle school students in Danbury were sickened yesterday by THC laced chocolate.  The school resource officer at Rogers Park Middle School assisted school administrators with an investigation into an unusual number of students feeling ill and seeking the nurse's assistance.  Police say the students became ill after ingesting some form of edible chocolate believed to contain THC.  The chocolate in question has been recovered by police investigators, who will attempt to identify its contents.   Students responsible for having distributed the chocolate were identified by school administrators and interviewed.  The investigation is continuing.
