DOG lovers in Estepona have been left horrified after a YouTube video showed a police van dragging a dog by its lead.

The Andalucia animal charity CACMA has now filed an official complaint against the officers involved and Estepona Mayor Jose Maria Urbano is said to be taking it ‘very seriously’.

It comes after the incident was filmed by a concerned resident on his camera phone and posted to YouTube where it has been widely viewed.

The disturbing video clearly shows the animal being pulled along the middle of the road while the van drives off.

“We were shocked and horrified to see how police dealt with this dog,” said Mary Page, Vice-President of local animal charity ADANA. “We hope that the incident will be thoroughly investigated.”
