A 20-year-old skateboarder has killed a 50-year-old man by hitting him over the head with his board in an apparent act of self-defense.
Witnesses said the older man was harassing people outside a Starbucks in Santa Ana, California, before punching a window and storming into the store in an aggressive manner.
Customers said the man 'aggressively approached' the skater who was having a coffee with his girlfriend then jumped to his feet and struck the man over the head with his board in self-defense.
Santa Ana Police Department Corporal Anthony Bertagna said the 50-year-old died at the scene and they confirmed a skateboard was involved.
The skater initially ran from the store after the confrontation yesterday afternoon but returned shortly afterwards and is cooperating with police. He has not been arrested.
Jocelyn Martinez was inside the Starbucks and told KTLA that the incident was 'really traumatizing'.
She said: "He just came abruptly into the store, looked at the kid, and said, "Did I stutter?"
"He took a step forward towards the kid as if he were going to attack him, and that's when the kid hit him with the skateboard."
She added: "He did what anybody... would do when they feel attacked. They're going to protect themselves."
A picture taken by a local CBS reporter showed a skateboard sitting on top of a police car outside the cafe. The Starbucks has been closed while cops investigate the death.
