Dodgers Beating Suspect Exonerated

Giovanni Ramirez is now officially off the hook for the beating of Bryan Stow outside Dodger Stadium on opening day.

Law enforcement sources tell TMZ ... the two suspects were arrested this morning and taken to Parker Center -- downtown L.A. police headquarters. They are both male Hispanics. At least one of them is in his mid-20's. Search warrants were served at 4 homes at 2 AM today.

Our sources say ... there was concern that the initial investigation was flawed, so the case was sent to the Robbery Homicide unit for a fresh look. We're told Robbery Homicide detectives "looked at the case from scratch, and the case against Ramirez fell apart."
