PICO RIVERA (CBSLA.com/AP) — Police arrested dozens of people protesting working conditions and wages at a Walmart in Pico Rivera Thursday after they allegedly refused to move from an intersection they were blocking.

Officers took 23 people into custody around 6:30 p.m. in the 8500 block of Washington Boulevard when they inhibited traffic at Washington and Paramount boulevards, sheriff’s Lt. Alex Villanueva said.

There also were reports of some Walmart workers, with mouths symbolically taped shut, staging sit-down strikes at other Los Angeles-area Walmarts.

A group supported by the United Food & Commercial Workers union are demanding a minimum wage of $15 an hour and full-time work for employees of the nation’s largest retailer.

An email to Walmart representatives seeking comment late Thursday night wasn’t immediately returned.
