14 Los Angeles High Schoolers Suspected of Sex Crimes

Los Angeles police made several arrests at an area high school Friday as part of an investigation into 14 high school boys accused of sex crimes.

The crimes–involving two underage victims—allegedly began over a year ago, police say many of the incidents occurred in the last two months, with several of the accused boys present. The police have also discovered photos of the sex acts, the Los Angeles Times reports.

Authorities were made aware of the incidents on Tuesday. The boys were not identified since they are minors between the ages of 14 and 17. The police arrested nine of the boys from Venice High School on Friday morning and a 10th turned himself in. There are still four more wanted in connection to the crimes.

The crimes are sexual assault and lewd acts with a minor, the Times reports. They involve a group of high school boys allegedly working together to pressure girls into having sex with them through a variety of threats.

The events allegedly occurred both on and off campus.
