The NBA is conducting its own inquiry into the events surrounding the arrest and injury of Thabo Sefolosha.

"We are working with the Hawks organization and local law enforcement to obtain more information about the circumstances surrounding Thabo's arrest," NBA spokesman Michael Bass said.

The league wouldn't go so far as to characterize its efforts as an official investigation, but a source close to the situation expects the league to do so in short order.

Sefolosha suffered a fractured right fibula and ligament damage early Wednesday morning in New York. 

Two videos have surfaced on TMZ that raise questions about the specifics at the scene. The most recent video, shot by a witness, appears to show Sefolosha being wrestled to the ground by five uniformed officers, after which one swings a baton forcefully, apparently at Sefolosha's lower body.
