Adrián Sánchez Quevedo had to be cut free by a team of firefighters after chaining himself to a traffic sign at the start of this year's Toro de la Vega, one of Spain's most controversial taurine festivals.
Fireman reportedly took around half an hour to release the 22-year-old, from Murcia, at a time when more than a thousand people were in close proximity to a rampaging bull.
The local delegation of the government of Castilla y León have imposed a fine of €5,200 ($5,488) on Sánchez for “posing a danger to public safety” under Spain's deeply unpopular Citizen Security Law - dubbed the 'gag law' by critics - which came into force in July.
Despite the severity of the fine Sánchez, remains undeterred.
"It strengthens my resolve to continue sabotaging these acts of animal cruelty," he told his local newspaper La Opinión de Murcia.
Meanwhile a local biscuit producer has been forced to change its name after animal rights campaigners launched a boycott on products from the town to protest at the cruelty of a tradition that dates back to the 15th century.
The famous shortbread-like biscuits known as polvorones will now be labeled El Toro instead of Polvorones del Toro Vega de Tordesillas.
The Toro de la Vega Festival, which is celebrated each September in the town of Tordesillas, near Valladolid consists of a bull being hunted through the town's streets by lancers, some on horseback and some on foot, whose aim is to lance the animal to death.
This year hundreds of animal rights campaigners flocked to the town to protest, resulting in clashes with police.
