Parents in Monmouth County say that they are upset over a series of videos posted online that depict high school students fighting.

More than 20 videos have been posted on Twitter that seem to show Neptune High School students punching, kicking and slapping each other. Other videos show teens being dragged by their hair.

The Neptune Township schools superintendent tells News 12 New Jersey that the fights all seem to have stemmed from last year and some may have been from outside of Neptune.

The superintendent says all incidents of violence on school grounds were addressed through discipline by the school or the police.

Neptune Township police say that the Twitter account that uploaded all of these videos has been deleted. The statement says that although the videos were posted over the span of about a month, many of the incidents took place over a year ago.

Police reiterated that all of the people involved in the fights were identified and charges were filed if warranted.

The superintendent says there has been no uptick of violence at the school in recent months.
