Officials say some New Jersey students have been participating in a violent social media trend where they fight one another and post videos online, calling it "Fight Week."

There were several cases at Dwight Morrow High School and Janis E. Dismus Middle School, according to superintendent Robert Kravits.

"The District provides daily monitoring of building hallways by administration, district staff, security officers and monitored by a video surveillance system," he wrote in a statement. "Incidents are acted upon quickly, comprehensively and professionally."

The schools are now working with Englewood police to put an end to the trend.
