JERSEY CITY - A young teen has been arrested for allegedly posting a video online of a sex act between him and a 13-year-old girl.

The Hudson County Prosecutor's Office says the 15-year-old Jersey City teen was arrested at Dickinson High School on Wednesday.

The suspect is charged with two counts of invasion of privacy.

Investigators say the video was posted on a social media website. Parents and students say they are both shocked and saddened by the alleged video posting.

The Jersey City School District Chief of Staff told News 12 New Jersey that the district could not comment on the case, but that it expects its students to be responsible consumers of technology.

The prosecutor's office says the investigation is still ongoing and that the teen was released into the custody of his mother.

He should appear before a judge in the next two to three weeks.
