Many of the 2,500-odd spectators at a bullfighting match in the Madrid suburb of Pinto were shocked Wednesday to discover glaring neo-Nazi graffiti spray-painted across the walls of the local arena.

According to Spanish media reports on Thursday, the words “Adolf Hitler was right,” accompanied by a large red swastika and the Nazi leader’s date of birth and death, were plastered across a section of the barrier surrounding the bullring.

Despite the disturbing graffiti, the stadium management decided to proceed with the fight as planned because, according to a municipal representative, “Thousands of people should not have to pay for the misdeeds of the few.”

The arena’s maintenance workers painted over the graffiti immediately after the conclusion of the bullfight.

The town mayor’s office issued a condemnation via Twitter, stating its “absolute rejection of the graffiti.”

A large assembly of local residents protested outside Town Hall, demanding that the perpetrators be brought to justice.

No suspects have been brought in for questioning thus far and it is unclear who was behind the offensive defacement of the stadium, police said.
