The 22-year-old former BC player was arrested Sunday shortly before the Eagles played Duke for violating an order issued in May, according to the campus police report.
Williams' Boston-based lawyer, Howard Fisher, said the player was invited to Sunday's game by a member of Boston College's coaching staff and blamed the arrest on "lack of communication" between the staffer and campus police.
The police report said Williams was belligerent when police tried to arrest him and wrote obscenities instead of his name on the fingerprint card and trespass warning.
"Maybe it's just human nature to act that way when someone is invited to an event and then placed under arrest," Fisher said.
The 6-foot-10 Williams was dismissed from the Boston College team in January 2007 for multiple rules violations that included an arrest for marijuana possession in 2005. That charge was dropped after he completed a rehabilitation program.
Williams posted $40 bail but failed to show for arraignment Tuesday. Prosecutors asked the judge to issue an arrest warrant, but the arraignment was rescheduled for March 5 -- the day after the Nets play the Celtics in Boston.
Williams and Nets coach Lawrence Frank had no comment in Houston, where the Nets played Tuesday night. Williams was the Nets' first-round pick in the 2007 NBA draft.
