Footage then showed Mr David standing still in front of the officers with his hands down at his side. He was carrying nothing in his hands and only had a backpack on him holding his ID and wallet.
One officer then started beating him with a baton when another sprayed pepper spray in his eyes, which encouraged the man to finally step away from the federal agents and move back towards the crowd.
The moment went viral after it was first shared on Twitter, with people calling Mr David “Captain Portland” and commending him for not moving when officers used aggressive force.
“That guy is a brick. And wow. Can’t believe that is how someone harmless-looking is treated,” one Twitter commenter wrote after viewing the footage.
Footage stopped with Mr David walking away, but that wasn’t the end for him.
