The Los Angeles Police Department said a teenage protester was stabbed and transported to a hospital in critical condition.

A 17-year-old boy is in critical condition after being stabbed Friday at a protest against President Trump's immigration and deportation policies near Los Angeles City Hall, authorities said.

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.
