NEW: "Anything that amounts to a violation of the law will amount to an arrest," school police say

Ten high school boys ages 14 to 17 are arrested on accusations of sexual assault

Los Angeles CNN  — 

Ten boys ages 14 to 17 were arrested Friday on accusations of unlawful sex acts against two underage girls for more than a year, on and off the campus of Venice High School, authorities said.

Eight of the nine male students were arrested on campus, and the other was taken into custody off-campus, police said. One suspect turned himself in.

Detectives have identified a total of 14 people, all between ages 14 and 17, who allegedly sexually assaulted the two female Venice High School students multiple times, said Cmdr. Andrew Smith of the Los Angeles Police Department.

Police have those names of the remaining alleged assailants, Smith said.

The investigation began Tuesday when school administrators told police about possible sex crimes involving students, police said.

Los Angeles Unified School District Police Chief Steven Zipperman told reporters that “student safety is our number one concern.”

“Any type of issues pertaining to sexual misconduct on any of our campuses will not be tolerated. It will be dealt with seriously. Anything that amounts to a violation of the law will amount to an arrest,” Zipperman said.

“Whenever there is an issue about student safety, we will do whatever we can to ensure that the behavior is stopped,” he added.

LAPD Detectives learned the alleged sex crimes occurred from December 2013 to this month, police said.

Police made “an effort to protect the victims” when making the arrests at Venice High School, Smith said.

The Los Angeles Unified School District is cooperating with police and the system’s school police, and the parents of the suspects have been notified, Superintendent Ramon C. Cortines said in a statement.

“This is a painful moment for Venice High School, and this District. I want you to know that no sexual misconduct of any kind by students or staff will ever be tolerated in L. A. Unified,” Cortines said.

Crisis counselors were on campus Friday to assist students, Cortines said.

Venice High School has been used as a filming location, including in the 1978 film “Grease” and the 2003 film “Matchstick Men,” according to
