Manhunt after 20 dogs tied to train tracks in Andalucia and run over by trains (WARNING: Distressing images)

AT least 20 dogs have been found mutilated and killed after being tied to train tracks in Sevilla.

They were found in several towns by PACMA, Spain’s leading animal rights party.

The corpses were found at train tracks in Espartinas, Olivares, Salteras and Villanueva del Ariscal.

Some still had the rope used to tie them to the railways around their necks.

At least one of the dogs had been used for hunting, which SEPRONA is investigating.

PACMA has also reported that several animals have been found alive.

¡Indignante! Aparecen 20 perros muertos atados a la vía del tren en Sevilla.

Una nueva forma de deshacerse de los animales que tanto "aman". Para los cazadores la crueldad no tiene límites.

PACMA has called for the chips from each dog to be investigated to help find those responsible.
