PORTLAND, Ore. — Portland police officers arrested three people during Friday’s Global Climate Strike rally and march.

Thousands of Portland students attended the event to make their voices heard on climate change. They gathered in Terry Schrunk Plaza and marched down Southwest Madison Street across the Hawthorne Bridge to OMSI.

The event was largely peaceful. Police said one demonstrator was treated by medics after being pepper-sprayed by another person. The suspect has not been identified.

During the march, a man vandalized the Hawthorne Bridge and fought with officers as they attempted to arrest him, according to police. Officers used a takedown and pepper spray to subdue the man, who identified himself as “Jake.” Police arrested him on charges of second-degree criminal mischief and resisting arrest.

Officers found several weapons in his backpack.
