He did not know what had been done with the ells after they were thrown.
The incident has left Collins street residents feeling confused.
One elderly woman said she heard cars late Sunday night and, a bit later on, other odd noises.
"I thought it was a dog or somebody in the bushes here, but I don't know anything about any eels," she said.
Another resident on the quiet suburban street was also bemused. "What a strange thing to throw at someone," he said.
Anyone with information about the incident is asked to call Timaru police station on 03 687 9808.
