A video has emerged of a father attacking children at a skate park in the north of NSW.

The man confronts the group of 12-year-old boys at the skate park in the Lismore suburb of Goonellabah, grabbing one child by the throat.

But the man was apparently protecting his son after he was bullied by the group.

Police believe the boys verbally abused and threatened the man’s son, eventually chasing him away from the skate park.

The incident occurred when the boy later returned to the skate park with his father.
