Some type of scuffle broke out, and one person — likely a student — wound up on the ground, bleeding from an apparent stab wound, according to video from the scene.

The Los Angeles Police Department said a victim was stabbed and transported to a hospital, but did not release any further details about the 1:30 p.m. incident.

Protesters swarmed the Spring and Main street overpasses of the 101 Freeway, with police on standby to prevent them from trying to walk onto the highway.
