Staff at an Essex aquatic centre were shocked to discover that someone had caught a Koi on the premises, then barbecued and eaten it, leaving just the head behind.
Tranquil Waters Aquatic Centre in High Ongar stocks high grade Japanese Koi. Its lakes contain over £100,000 worth of Koi.
Manager Allan Joyce told Brentwood Gazette: "To have someone come and fill their stomachs on one of them is sickening.
"We have had to step up our security and have now got a new watchman who will be staying on site at night.
"It's devastating to have this going on, we don't know if they will come back, if this will be an on-going thing.
"We just want to warn residents and let them know to keep an eye on their ponds."
The fish was estimated to have been worth around £200.
