Four students and a teacher were arrested Saturday in connection with an alleged in-classroom hazing incident at a Fontana high school, police said. Police did say they believe the incident involved students in a summer school class that began May 31, and that a teacher, identified as 27-year-old Emmanuel De La Rosa, "facilitated some students to carry out the hazing to limit behavioral problems within the classroom." After interviewing students in the class, detectives identified four students who "actively participated in the assaults," police said. Updated, 6:50 p.m.: All three of the victims were male juveniles whose injuries were minor and did not require hospitalization, said Fontana police Sgt. Robert Morris. [For the record, 6:49 p.m.: A previous version of this post incorrectly said the arrests were made Friday. Also, De La Rosa was misidentified as Emmanuel Del Rosa.] Murder-suicide at Beverly Hills hotel remains a mystery Creators of mystery guerrilla street art in L.A. revealed
