The animal was seen stealing three six-packs of beer from campers before ransacking rubbish bags for food.
One camper reported seeing the pig guzzling the beer before getting involved in an altercation with a cow.
"In the middle of the night these people camping opposite us heard a noise, so they got their torch out and shone it on the pig and there he was, scrunching away at their cans," said the visitor, who estimated that the pig had consumed 18 beers.
"Then he went and raided all the rubbish bags. There were some other people camped right on the river and they saw him being chased around their vehicle by a cow." more at url
