There were no immediate reports of injuries, but police were turning away customers to the market as they deal with the standoff.
The Hollywood Farmers Market said its vendors and staff were safe. Police said the standoff was taking place on the 1600 block of Cosmo Street.
“We’re glad our staff and vendors are OK,” the market said on Facebook. “If you need access to fresh food and produce and can travel, please visit our sibling market Atwater Village Farmers’ Market.”
