A Chicago police spokesman said Darrell Gibson got into an altercation with a woman who sustained minor injuries, according to the Chicago Sun-Times. A video of the incident was uploaded to YouTube but was quickly removed as a violation of the site’s terms of use. It has since resurfaced on other sites.

Live Nation, which owns the House of Blues chain, said it is looking into the incident. The company released a statement saying, “We take our responsibility to maintain the safety of both our patrons and the artists who play at the House of Blues very seriously … and will cooperate fully with the authorities.”

The scuffle apparently began when the security guard attempted to confiscate the woman’s camera. Hanson was playing the HoB the night in question, but police didn’t confirm the woman attended the show.

The video shows the two engaged in a shouting match and what appears to be the guard knocking the woman to the ground.
