WOODSTOCK, Ga. (CNN/WUSA9) -- Parents are outraged after reports that two freshmen at a Georgia high school engaged in a sex act in the school cafeteria while another student recorded it.

Students who witnessed the incident said the teens involved stacked books and backpacks to keep the two freshmen hidden from view. Some other students at the same table apparently didn't know what was happening.

Students say the sex act happened because someone dared the female student allegedly involved. Students also say the news of the alleged incident, and the video, spread quickly.

The school district confirmed in a statement that two juvenile students were charged with misdemeanor public indecency. The school said it will take its own disciplinary action.
