A 39-year-old man from Los Villares, in Jaén province in Andalucia, southern Spain, uploaded photos of the wet paintings to Facebook, according to the Guardia Civil.
The cave paintings in the Sierra Sur de Jaén mountain range are protected on the country’s heritage register, and the man is under investigation for a crime against historical heritage.
Officers from the Guardia Civil’s nature protection service (Seprona) launched an investigation in May after seeing the photos online.
The law enforcement agency called on residents to report any signs of damage or vandalism to cave paintings to protect Spain’s historical heritage.
