The report says Dennis O’Brien and John Esposito began arguing Sunday and O’Brien swung at Esposito with the tool in his right hand.

Authorities say Esposito suffered a swollen left eye and cuts on his nose and mouth.

Esposito said both he and O’Brien worked at Wal-Mart. He would not discuss the nature of their argument.

The report says O’Brien told a sheriff’s deputy he acted in self-defense, but security tape showed O’Brien raising his hand first, striking Esposito in the face and then pushing him to the ground.
