San Juan Police Officer Angel Nazario said the woman claimed Williams snatched the camera, damaged it and hit her in the face. The incident allegedly happened around 2:30 a.m. Thursday at a San Juan nightclub, hours after the Puerto Rican team beat the Netherlands 5-0 in the World Baseball Classic.
Williams, who is playing for Puerto Rico, left with the team on Thursday for Miami. It will play the United States in the tournament's second round.
San Juan Police Officer Marisol de Jesus said police are investigating.
