WASHINGTON: A logging contractor in the US took neighbourly score-settling to a new level when he jumped into his bulldozer and demolished two houses, flattened a truck and snapped an electricity pole, causing power cuts across a 30-kilometre radius.

Neighbours in Port Angeles, 130 kilometres north-west of Seattle, said a boundary dispute was behind the rampage.

Police said Barry Swegle, 51, was being held on suspicion of "malicious mischief in the first degree" after allegedly firing up his bulldozer with "skidder" attachment and setting to work.

Aerial pictures showed that one property was ripped off its foundations and shunted more than 100 metres into a neighbouring plot.
