A fight broke out inside Baltimore's Horseshoe Casino on the first weekend after its grand opening.
A video of the incident shows security guards wearing yellow shirts rushing to break up the fight, which occurred in the line for Pie-Zetta, a pizza restaurant, around 3 a.m. Saturday.
"Basically, somebody said something ... to one person and they took it the wrong way," said Kevin Forrest, who witnessed the fight. He said a woman sprayed mace before about 20 security guards stopped the fight and escorted people out of the casino. Forrest, who goes by the nickname "Hollywood," took the video and posted it to Facebook, where it was shared more than 400 times by Sunday afternoon.
