A 15-year-old girl stabbed a helpless calf for entertainment at a bullfighting event.
Distressing footage shows the exhausted cow already pierced by four banderillas as the girl repeatedly tries to skewer him with a sword.
The animal endures at least seven more stabs before he collapses at the sick event in Esquivias, Spain.
The clip also shows children being presented with gruesome trophies – ears hacked from the dying calves, each of which was less than two years old.
Since the footage emerged, Animal Guardians and La Tortura No Es Cultura (Torture Is Not Culture) has pleaded with authorities to act.
The activists spokeswoman, Marta Esteban, said: "Would we consider it a form of entertainment to see boys and girls torturing dogs and cats, or even sheep?
"Why is it different with cattle? It clearly is not.
