The provincial headquarters of the Spanish Socialist Workers' Party in Ávila was defaced overnight with abusive graffiti branding members traitors, murderers and brothel clients.
Government officials confirmed that the vandalism was the only significant incident recorded across the province during the start of a general strike on 11 November.
The offensive slogans were discovered on the morning of the strike daubed in large lettering across the entrance door and the exterior facade of the building. Leaders of the local party branch lodged a formal criminal complaint with Spain's National Police shortly after discovering the damage.

Socialist party response
Carlos Montesino, the secretary general of the Spanish Socialist Workers' Party in Ávila, condemned the attack and warned that it should not be dismissed as casual vandalism. He said the graffiti represented a clear act of hatred and intolerance intended to single out, intimidate and frighten people who champion a legitimate democratic project.
Montesino said that those who resort to intimidation show an inability to accept democratic rules or respect political pluralism. He added that nobody in a free society has the right to force their views on others through insults and threats, stressing that while political debate is healthy, violence and hatred are never acceptable.
The Spanish Socialist Workers' Party, known as PSOE, is Spain's main governing centre-left party. Local party branches across Spain maintain public headquarters in provincial capitals such as Ávila, a historic city in the autonomous community of Castile and León located northwest of Madrid.
Warnings over political violence
Manuel Arribas, the socialist candidate for the Congress of Deputies, Spain's lower house of parliament, also condemned the vandalism during an interview with local radio station COPE Ávila. Arribas warned that the incident must not be tolerated because there is only a short step from aggressive graffiti to physical violence against individuals.

Arribas said the messages daubed on the building reflected growing political hostility. He warned that the slogans offered a preview of what could happen across the country if right-wing and far-right parties took control of the national government of Spain.
The Congress of Deputies is the primary legislative chamber of the Cortes Generales, Spain's national parliament, holding 350 seats representing constituencies across the country. Tensions between the governing socialists and conservative rivals have repeatedly flared outside party premises nationwide in recent years.
General strike in Ávila
The attack occurred against the backdrop of a nationwide general strike called for 11 November, known locally as 11-N. In Ávila, the provincial subdelegation of the central government reported that the strike had started peacefully overnight, with no disruptions to public order across either the provincial capital or surrounding municipalities.
Government representatives noted that informational pickets had assembled at several designated locations throughout the province to monitor workplaces and distribute material. Authorities confirmed that none of the picket lines had caused disturbances or reported any conflicts during the early hours of the stoppage.
Official participation figures for the industrial action were not immediately available as morning activities got under way. Officers from the National Police are investigating the vandalism at the party offices, while local authorities continue to monitor the progress of the general strike.
