The men currently in custody -- 29-year-old Louie Sanchez and 30-year-old Marvin Norwood.
Both men are being held on $500,000 bail for the beating of Bryan Stow (above) on opening day.
TMZ has learned ... Norwood has been arrested in San Bernardino County 5 times, including one for spousal abuse. He was convicted for spousal abuse and various DUI and drug charges.
Sanchez has been arrested 9 times in San Bernardino County, and he has an arrest for spousal abuse. Sanchez was convicted on spousal abuse and firearms violations, including carrying a LOADED gun in a public place.
All told, Sanchez has been arrested by THREE different police departments in THREE different cities.
Giovanni Ramirez -- the man whom the police chief said did the vicious deed -- has been exonerated. It is a big embarrassment for the LAPD.
