-- Mike "The Situation" Sorrentino allegedly got into a "fist fight" with his brother right before his arrest Tuesday at a New Jersey tanning salon, according to the 911 tape obtained by ABC News.
A customer called the police to report that the "Jersey Shore" star, 31, got into a fight with his brother Frank "with like family trying to pull it apart in the back" of Boca Tanning Salon.
Sorrentino was taken into custody yesterday in Middletown, N.J., where he is opening a franchise store of Boca Tanning, authorities said.
Today, the reality star was seen with quite the shiner under his right eye.
"There [were] girls screaming," the customer says on the tap, adding that's why she called. "The UPS lady from next door was like they were bouncing off her wall. I was just the one that made the call 'cause I had the phone out."
Sorrentino was charged with simple assault and released on $500 bond. A rep for Sorrentino said he would have no comment on the situation.
A video posted by TMZ shows Sorrentino explaining the fight happened because "brother Frank, the HR was not running the store correctly, so I had to go in there and clean house" and he joked that his brother Frank, "Don't look too good."
