Police said Sullinger arrived at the police station 6 a.m. Tuesday to turn himself in. Sullinger is charged with assault and battery, malicious destruction of property and witness intimidation.
According to police, the incident happened early Saturday evening.
Sullinger, who averaged 6 points and almost 6 rebounds per game in 45 games as a rookie last season, is scheduled to be arraigned Tuesday in Waltham District Court.
Sullinger, 21, had back surgery in January after questions regarding the condition caused his stock to plummet in the 2012 draft all the way to the Celtics at No. 21. He had a productive season and was seen as a bright spot prior to the injury.
