MANSFIELD - New England Patriots defensive back Willie Andrews allegedly pointed a 9 mm handgun at his girlfriend's head after she accused him of cheating on her at his Mansfield residence this morning.

The woman, 23, told police she and another woman confronted Andrews in the children's bedroom of his apartment at 10 Connors Ave. Sunday night after discovering he was cheating.

The woman told police she and Andrews had been engaged for a month and a half, and have a child together. They have been together for about three years.

"He came home and was waving a gun (9 mm Glock) and touched my temple. He continued waving the gun as he started throwing my items into my suitcase and onto the floor," the woman wrote in a statement to police.

Police responding to the woman's 911 call said they saw Andrews near garages across from the building at 10 Connors Ave. When they advised him of the allegations, Andrews verbally agreed to allow police to search his car. They did not find a gun in the car or the surrounding area.

After police talked to Andrews, the woman left with her child to stay at a hotel.

Early this morning, police saw Andrews talking to the woman in the hotel parking lot while she was in her car.

When police arrived, Andrews walked away from the car and left.

Police spoke to the woman again. They asked if she was in fear, and she said yes "because he has threatened to shoot her in the past."

The woman then wrote a voluntary statement about the incident.

Police returned to Andrews' apartment, where they arrested him without incident and charged him with assault with a dangerous weapon.

He was held overnight without bail.

Andrews was scheduled to be arraigned this afternoon in Attleboro District Court.

The arrest was Andrews' second this year. In February, he was charged with possession of marijuana with intent to distribute after police allegedly found him with a half-pound of marijuana during a car stop. In May, the case was continued without finding after Andrews reportedly admitted to sufficient facts for a guilty finding.

Andrews, 24, was drafted by the Patriots out of Baylor University in Texas in the last round of the 2006 NFL draft. He has played mainly on special teams for the Patriots, the highlight being a 77-yard kickoff return for a touchdown last Oct. 10 against the Miami Dolphins.
