Freer said he had asked a couple of young people to leave the mall because they were causing a disturbance.
"One of them followed me back to the office and hit me from behind and kicked me, when I turned around, half a dozen of his mates were there coming at me as well."
The incident had been a shock. "I think we all sit on the fringe of this sort of thing until it happens to you ...
"The first thing I asked was 'what sort of thrill does a teenager get from bashing a 60-year-old?

"There's lots of opportunities, let's channel that aggression into something positive."

Freer is a mayoral candidate for the upcoming Thames-Coromandel District Council elections. Asked if he thought councils had a role in finding possible solutions to disruptive and harmful behaviour by youth in a community, he said councils had changed significantly.
"There are lots of health and wellbeing and community issues that council haven't considered and need to be considered in the future because we can't rely on the Government to deliver. This falls into that category. I believe councils and community boards have to move into this space if it's going to be an issue moving forward.
"We live in a semi-tourist town, we've got to make sure our reputation is high, we want people to come to visit our area, so we've got to make sure we stop this, so we don't become known as a place that isn't safe."
