A Bangor woman said that her live-in boyfriend returned home from a successful job interview very happy Tuesday afternoon, but became enraged and physically violent after he felt she wasn’t happy enough at his landing a job, according to police.

At first Michael Willis, 20, yelled that she wasn’t supportive of him, the woman told Officer Tim Cotton. Later, when she told him he needed to take care of their 21/2-month-old son that night, he tipped over the chair she was in, then pulled it back up. The girlfriend said that she threw a diaper at him, and Willis, holding their infant son, slapped her across the side of her head, hurting and stunning her for about 30 seconds, according to the police report.

The 19-year-old girlfriend said Willis also grabbed her by the arms and restrained her. At one point he covered her mouth with his hand, so she couldn’t speak, the woman told Cotton. She fled the home and ran to the Spruce Run battered-women’s shelter, where the police were called.

Cotton spoke to Willis at his residence at 83 Somerset St., but Willis denied anything physical occurred other than his girlfriend throwing the diaper at him. Cotton arrested Willis, charging him with domestic assault.

The girlfriend reported later that Willis had thrown their infant at her and that their son had bumped his head against the arm of the chair she was sitting in.

Another domestic assault case was reported in Bangor, occurring early Tuesday morning after a woman said she returned home and found her angry boyfriend there.

Kyle Rand, 27, of Bangor faces a charge of domestic assault after his girlfriend of several months said he “got in her face” and pushed her to the floor. The woman told Officer Douglas Moore that Rand confronted her about not being home all day.

She said Rand grabbed her by the arms and around the neck and she showed the officer a bruise on her right triceps. When she came into the police station about 1 a.m. Tuesday, Moore noted that her neck, upper chest and right side of her face had red marks as if fingers had been dragged across them.

Rand claimed that he had been assaulted by his girlfriend, showing Moore a cut on his arm he said came from when he was thrown down the stairs. The woman had told Moore earlier that during the incident, Rand had thrown a picture frame and used the shattered glass to cut his own arm.
