This is the moment a bull runner was left humiliated when a raging animal ripped off his trousers and underwear in an arena in Spain.

Footage taken in Zaragoza, in the north of the country, shows the entertainer being carried along on the bull's horns for several metres while members of the audience scream.

Seconds later he is dumped on the ground before the angry animal wrenches its head sideways - pulling the man along the sandy ground and ripping his clothes off in the process.

Helpers rush in to distract the creature as the semi-naked victim drags himself free and limps to safety with his trousers around his ankles.

He can then be seen vaulting over a barrier as onlookers laugh. Video posted on YouTube by Planetatoro Toro suggests the incident happened on Monday.
