BOSTON (AP) _ Boston Celtics center Vitaly Potapenko faced charges of disorderly conduct after arguing with his girlfriend at Logan International Airport this morning, authorities said.

Potapenko reportedly was seen arguing with a woman in one of the airport's terminals shortly after midnight, State Police Sgt. Edwin Anderson said.

Anderson declined to identify the woman, but said she was Potapenko's girlfriend.

Massachusetts Port Authority employees called state police to break up the altercation. When troopers arrived, Potapenko and the woman were in a parking lot. When Potapenko refused to leave, troopers arrested him, Anderson said.

Potapenko was released on his own recognizance, and scheduled to be arraigned later today in East Boston District Court.

After being released, Potapenko returned to the airline terminal to try and intercept his girlfriend, police said. He did not see her, and a trooper told him to leave.

A telephone call to the Celtics was not immediately returned.

The Ukrainian-born Potapenko, 24, was traded to Boston in March from the Cleveland Cavaliers. In 33 games with the Celtics last season, he averaged 10.7 points and 7.3 rebounds.
