A mail carrier in Southern California was seen on video fighting back against a man who viciously attacked him in what appeared to be an unprovoked assault, according to a local report.

The mail carrier, who has not been identified publicly, is seen walking down the driveway of a home in Gardena as a man waits for him near the street, according to home surveillance video obtained by FOX11 Los Angeles.

The unidentified man approaches the mail carrier and makes comments as the victim tries to walk past him on his route, the video shows. The man also fakes throwing a punch at the mail carrier as he walks by.

When the mail carrier turns his back and continues to walk away, video shows the man following him and punching him in the back of the head. The hit causes the mail carrier to drop an armful of mail onto the street.
