QUESNEL, British Columbia (AP) _ She locked him out of the house. So he tore it down with his bulldozer.

Mildred Stychyshyn said her boyfriend, an unemployed bulldozer operator, was mad because she wouldn't let him in when he came home drunk. So he started up his bulldozer and smashed her wooden house to pieces, she said.

''He told me that if he couldn't live in the house, neither could I,'' Stychyshyn said.

Police arrested 50-year-old Leon Roger Hetu on Friday night after he leveled the house in Quesnel, 260 miles north of Vancouver, police Constable Paul Collister said. He told police he couldn't stand Stychyshyn's nagging any more, Collister said.

It wasn't the first time Hetu went after Stychyshyn's house with his bulldozer. Two months ago, he took off the corner where her master bedroom had been. One of the conditions of his probation was to rebuild that section of the house, but instead, he apparently decided to finish off the razing job, Collister said.

Hetu, 50, was charged with mischief endangering life, RCMP Cpl. Ken Brown said Sunday.

Stychyshyn lost almost everything and had no insurance. She was staying with a daughter in Quesnel, and neighbors have started a home-replacement fund.
