ALEXANDRIA, Va. (DC News Now) -- Alexandria City High School moved all in-person classes to online learning for Thursday and Friday this week, after students and staff were injured during several altercations. Several students unaware that classes had been moved online showed up to the King Street campus of the High School on Thursday. "I didn't know notice that," said an Alexandria City High School senior. Three additional people arrested in connection to deadly Manassas shooting This comes after several altercations took place on Wednesday. The Alexandria Police Department (APD) said at around noon, two School Resource Officers (SRO) responded to reports of "multiple physical altercations occurring in school hallways and the cafeteria." In a letter to parents, Superintendent Dr. Melanie Kay-Wyatt for Alexandria City Public Schools said students and staff were injured. APD said one student left with their parents to receive treatment at a clinic. A woman who was seen in a video on social media lying on the ground refused medical attention at the scene and declined to file a police report. APD said they are continuing to verify the validity of a report that a student was stabbed, but as of Thursday, had not found anything substantiating that claim. To ensure safety for everyone the school was placed on a "hold status" for most of Wednesday despite the altercations involving a small number of students at the King Street campus. A senior said she was on her way to class when she saw a fight break out, adding, "It was kind of scary but not too much." Alexandria high school cancels in-person classes due to ‘student altercations’ Superintendent Kay-Wyatt went on to express in the letter her disappointment in students, and that disruptive behaviors will face consequences. "I would also like to express how disheartening and concerning it was to learn about the unacceptable behaviors and actions taken by some of our students that resulted in injuries to staff and students. Our school community deserves better and counts on us to provide a safe place for teaching and learning," she wrote. The letter went on to say additional measures will be implemented for when students return back to school after winter break in January. APD said two students were charged with assault and battery for their involvement in the fights on Wednesday. Police added they would be increasing their presence in and around neighborhoods of ACHS and within retail spaces to deter and prevent further incidents.
