KCBS’ Bob Melrose Reports:

A 25-year-old pizza delivery man, Shaun Cass,  said the trouble started when he wore a jersey with the name of Laker Kobe Bryant to the game.  Cass said he was taunted during the game, and after the game, which the Warriors won, he was confronted by three men outside the arena.

Cass said one man sucker punched him, breaking his jaw. He said the security guards at Oracle Arena did nothing to help, and told him a police report would take three to six hours to file.

A spokeswoman for Oakland Police Department said the department wasn’t notified until a report was filed three days after the incident.
