Disturbing video footage captured the  that left two students injured and two in custody at Westchester Community College on Wednesday.

Several students are seen scuffling on the ground outside the David Swoope Student Center at the suburban college – with one stumbling away and falling to the ground covered in blood as other students repeatedly yell, “Stop!”

“They had a knife,” one woman is heard yelling.

“I was just on my way back to class and then we see a fight break out,” one student eyewitness said. “The two boys dropped to the floor, and there was just blood everywhere.

“I rushed to the boy that’s bleeding the most,” she said. “He was just bleeding out and somebody passed me a sweater and I’m just trying to stop the blood. And the two that did it are just like running around. It’s insane.”

The student said one victim was stabbed in the back and another in the head, she said.

“I think they were arguing just over the course of two days and it built up into a fight,” she said.

Among the eyewitnesses to the 𝘴h☉𝔠king melee was someone bizarrely dressed as “Chester the Viking,” the community college’s mascot.

Westchester County police said they responded to a 911 call at the Valhalla campus around 12:40 p.m., where they found the two injured students and took the suspects into custody.

The combatants included both current and former students.

The victims were taken to Westchester Medical Center, where one is listed in serious condition and may require surgery, police said.

The two suspects were taken to Phelps Memorial Hospital in Sleepy Hollow with lacerations but no wounds, with charges now pending against both as of Wednesday evening, cops said.

In a statement, college officials said county cops were leading the investigation “with the full cooperation and support” of the school.

“Our top priority is ensuring a safe and welcoming campus environment for students, faculty and staff,” the statement said. “There was an incident on campus that has been resolved.”

Police have not revealed what may have sparked the brawl.

“It was just like random,” another student said. “I don’t know why. You never think it happens to you or near you until it does.”

The 80-year-old college is part of the SUNY system and has about 9,700 students.
