Police in Scottsdale confirmed they are investigating an incident that occurred this past weekend at a nightclub.
The incident happened at around 2:30 a.m. Saturday, Scottsdale police spokesman Officer Kevin Watts said.
It was "far too early in the investigation" to confirm what Harden's involvement in the incident was, Watts said.
According to TMZ, a woman said she was at a nightclub in Scottsdale when someone with Harden got into a fight. The woman was recording the scuffle when Harden walked up, grabbed her wrist and phone before throwing her phone onto a roof.
The woman was treated for a wrist injury at an area hospital, TMZ said.
