Just about two hours after that assault, Los Angeles County sheriff's deputies based in West Hollywood arrested Shoner for a different alleged assault at Santa Monica Boulevard and Spalding Avenue.
The two agencies did not make the connection until after the Los Angeles Police Department put out a public release and surveillance video on the Hollywood incident on Wednesday.
Shoner is being held on $190,000 bail on charges that include robbery, criminal threats and assault with a deadly weapon.
