For the second time in a month, a Pittsburgh-based Mexican restaurant and grocery chain has been vandalized.

On Friday, a large rock was found thrown through a window of Las Palmas Casa Rasta restaurant in the city's Beechview neighborhood, Channel 11's news exchange partners at TribLIVE reported.

The Las Palmas grocery store in Brookline was targeted in December, when the words “Go back to Mexico now” were written on the business.
