Lionel Wright, 26, was booked into West Valley Detention Center in Rancho Cucamonga on suspicion of robbery, San Bernardino County sheriff's officials said.
The victim got in his car after leaving San Manuel Indian Bingo and Casino about 8 a.m. Monday. Wright, who was in another car, rear-ended the victim at the corner of Base Line and Boulder.
When the victim stopped, Wright got out, ransacked the victim's car in search of casino winnings, attacked him and then snatched his car keys, sheriff's officials said.
Authorities obtained a warrant for Wright's arrest. He was captured by Chino police Wednesday.
