Employees had organized a demonstration outside the store as part of a nationwide protest organized by the union-backed group OUR Walmart.
Lakewood Boulevard at Rosecrans Avenue was shut down around 12 p.m. as protesters filled the streets.
Deputies moved in and arrested nine people who sat on the ground and refused to move, accusing the corporate giant of intimidation and bullying.
One of the people arrested told KTLA that it was his first time being arrested but felt it was “important to get the message out there” and that they are not being “respected as employees.”
Walmart issued a statement Friday, saying that the company had a successful Black Friday despite the growing tension.
