Mike "The Situation" Sorrentino has been arrested after a physical altercation at the Boca Tanning Salon in Middletown, New Jersey.
"On Tuesday afternoon we responded to a 911 call at Boca in reference to a fight in progress. Upon arrival, our officers arrested Mike Sorrentino for simple assault," Detective Lieutenant Steve Dollinger tells PEOPLE. "He is in the process of posting $500 bail and the matter will be set for a court date."
The former Jersey Shore star got into a brawl with his brother, Frank, at the tanning salon, TMZ reports.
Sorrentino, 31, gained fame for flaunting his abs and pumping his fists on the MTV show, which ran from 2009-12 and also featured Nicole "Snooki" Polizzi and Jenni "JWoww" Farley.
Sorrentino is set to return to reality television on July 15 for TV Guide Network's The Sorrentinos, which will follow his family members as they try to open their own tanning salon – and support his sobriety following a 2012 stint in rehab.
