Video posted to several social media sites showed Hernandez on the floor of the gym bathroom as at least two men kicked him and grabbed him by the hair.
The sheriff's office said the rapper was treated for non-life-threatening injuries.
The rapper was a social media phenomenon with millions of followers on Instagram before becoming an ascendant name in hip-hop.
He had a multiplatinum hit song, "Fefe," with Nicki Minaj, which peaked at No. 3 on the pop charts, and "Stoopid," featuring the incarcerated rapper Bobby Shmurda.
Lazzaro told TMZ that the rapper, who did not have personal security with him, tried to fight back during the attack but was overpowered and outnumbered.
The rapper was released early from federal prison after he cooperated with law enforcement officials during an effort to prosecute fellow gang members.
