"The Sandlot" star who has been charged with felony assault helped beat a grad student within an inch of his life ... according to new legal docs.
Michael Vitar, who played Benny "The Jet" Rodriguez in the flick, allegedly attacked the 23-year-old USSB student on Halloween night.
According to a search warrant obtained by TMZ, 2 of Vitar's friends, both of whom are firefighters, spotted Samuel Chang passing out candy in the street of his gated L.A. community. The firefighters suspected Chang was passing out tainted candy and confronted him.
The warrant claims the 2 firefighters began beating on Chang, restraining him with a chokehold. The legal docs claim Vitar -- now a firefighter as well -- joined in, mid beating.
The warrant says the beating was so bad Chang's pulse stopped and the firefighters had to get their gear and revive him.
Chang was taken to the hospital with horrific injuries, including burst blood vessels in the eye, bleeding on the brain, kidney failure and hemorrhaging due to suffocation.
Chang had recorded the audio of the beating on his cell phone, and cops believe they can hear Vitar say, "I got the legs."
The student says he smelled alcohol on the breath of one of the firefighters. The firefighters told cops they believed Chang was under the influence of PCP, but doctors found no drugs in his system.
