"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."
According to a police report, officers responded at 2 a.m. ET to a fight call at 6am, a hookah bar in Brookhaven, Georgia, where Schroder lives.
The report says a security camera caught Schroder and several others in a heated exchange with the victim. The report says Schroder initiated physical contact by shoving the victim. The video also showed Schroder and the others striking the victim with their hands and feet, according to the report. Security intervened and pushed Schroder and the others away from the victim, the report says.
The victim suffered scratches to his right knee and complained of right ankle pain, according to the report.
In an email to ESPN, Brookhaven police said they will not yet be releasing the video of the incident because of pending prosecution.
Schroder played in 79 games for the Hawks last season, averaging 17.9 points and 6.3 assists in his first season as a starter.
