A herd of wild boars is running amok in the Polish city of Swinoujscie.

Over 80 of the beasts have invaded the city, forcing the authorities to set up a wild boar task force to bring them under control.

The mayor of this northern port city says the invasion, which started over the summer, is making life increasingly difficult for both tourists and residents, and he is "at the end of his tether".

Earlier this year, the city was forced to pay out compensation to a tourist who was bitten by one of the animals while trying to pet it.

Recently, residents of a block of flats were held hostage in their homes when a rogue boar burst into the building and ran up and down the corridors for hours.

When they're not digging up grass in the public park, the herd spends its time roaming the beaches and waiting around fast food stands for leftovers.

Mayor Mozejko says the wild boars migrated to Poland from neighbouring Germany in search of a better life after German foresters stopped feeding them.

The newly-established wild boar task force wants to move the animals to a neighbouring forest but officials are not optimistic.

Wild boar can weigh up to 100 kilos and are extremely difficult to catch.
