GARDEN GROVE, Calif. (KABC) -- Troubling video now coming to light shows a group of students from a Garden Grove high school giving Nazi salutes while singing a Nazi marching song.The eight-second video shows about 10 boys from Pacifica High School's water polo team at an off-site awards ceremony in December. No coach or adult is in view.The teens appear to be gesturing, using a Nazi salute and singing a Nazi marching song once used to play for German troops and Adolf Hitler during World War II.The video has since been taken down.The school has about 1,650 students. Classes resume next week."I'm shocked that something like that would happen at our high school," said Mike Chambers, a former student and former parent at the school who lives nearcampus."That's one thing that kids just don't understand nowadays. Anything you post ... at some point in time, it will come out."A spokeswoman for the Garden Grove Unified School District released a lengthy statement that reads in part:"Garden Grove Unified School District and Pacifica High School strongly condemn a video recorded last year of some students who engaged in offensive Nazi-related gestures."The school says the video was shared with a small group of students on Snapchat and didn't come to the attention of the district until March 2019 "at which time school administrators took immediate action and addressed the situation with all students and families involved."The district said federal law prohibits disclosure of the disciplinary actions taken against students.This is the second incident involving teens and Nazi gestures
