Coffee cart owner Linda Jenson and hot dog cart operators Letty and Pete Soto said they initially provided free food and drink to demonstrators, but when they stopped, the protesters became violent.

And according to one city councilman, bodily fluids were used in the attacks.

“Both carts have had items stolen, have had their covers vandalized with markings and graffiti, as well as one of the carts had urine and blood splattered on it,” said Councilman Carl DeMaio.

The damages will likely require at least a complete cleaning if not a replacement of the cart covers, DeMaio said.
