Cape Cod Koi Pond Poisoned With Soap, Police Investigating

YARMOUTH, MA — Yarmouth police have opened an investigation after a residential koi pond was poisoned over the weekend, killing at least two fish.

Yarmouth officers responded to an address on Pleasant Street on Sunday after the homeowner reported that either soap or detergent had been dumped in their koi pond.
