The SPCA is asking for information from the public after two men used a remote-controlled jet boat to fatally injure a swan at a local park's pond.
Tamatea local Nicole Penman, who lives near Anderson Park and often walks her dogs there, was one of three witnesses to the "horrific crime" at the park pond last week.
"I was taking my dogs for a walk. Usually the jet boats go out on the pond and none of the ducks are in the pond.
"On this particular Sunday, I don't know what made me stop, but I stopped to look at this guy hooning around on the pond with his massive red jet boat.
"I saw him circle around some of the swans and they didn't move, so he circled a buoy, I think to get a bit of speed up, and then he hit a swan."
