Dennis Schroder was charged with misdemeanor battery in an Atlanta suburb early Friday morning, court records show.
"We are aware of an incident involving Dennis Schroder earlier this morning," the Hawks said in a statement. "We are still gathering information as it pertains to the situation, and out of respect for the legal process, we will have no further comment at this time."
Schroder allegedly had a confrontation at a hookah bar.
The report says a security camera caught Schroder and several others in a heated exchange with the victim.
