TORRANCE, Calif.–Vandals plastered graffiti on an exterior wall at a Chick-Fil-A restaurant in Torrance, police said today.

The graffiti was discovered this morning at the Chick-Fil-A at 18200 Hawthorne Blvd., said Torrance police Lt. Martin Vukotic.

Someone painted “Tastes like hate” with a picture of a cow next to it on the front exterior wall of the restaurant.

There are no known suspects, Vukotic said.

Torrance police will be monitoring all of the Chick-Fil-A restaurants in Torrance today, according to Vukotic.

“We have extra patrol for all three of our locations in our city,” he said.

Chick-Fil-A has been mired in controversy in recent days as a result of comments made by Dan Cathy, the company’s Georgia-based owner, who has spoken out against same-sex unions.

A national “kiss-in” is planned today at Chick-Fil-A restaurant locations, including those in Los Angeles, according to organizers. It envisions gay rights supporters showing up at the restaurants and kissing a demonstrator of the same sex.

Supporters of the fast-food chain organized a “Chick-Fil-A” Appreciation Day on Wednesday, with thousands flocking to the company’s restaurants.
