8:13 a.m. Los Angeles police say an eleventh teenager sought in connection with sexual assaults that allegedly took place at a high school has turned himself in.
Sgt. Eric Rogers says the boy was booked Monday evening but other details aren't available.
Ten other boys, ranging in age from about 14 to 17, were arrested or surrendered to investigators last Friday and have been released to their families. Three others are being sought.
Investigators believe the assaults took place on and off campus at Venice High School, beginning in December of 2013 and continuing into this month. They involved two teenage girls at the school.
Police believe some of the sex acts were forced and others were consensual but involved victims who were too young to legally give that consent.
