A recent mystery concerning two goldfish being found in a restricted area of a nuclear power plant has been solved and found to be a prank from work men.
The goldfish were found in a jug of radioactive water in a secure area of Perry Nuclear Power Plant outside Cleveland.
It is thought that six contractors were responsible for the stunt, smuggling the fish in inside lunch boxes.
FirstEnergy Corp. spent a month investigating where the fish came from, with federal regulators also getting involved.
The company said the contractors, hired to replace insulation on pipes for inspections, admitted to bringing the fish into the plant as a prank.
They avoided security measures designed to look for explosives, guns and other contraband that would cause damage to the power plant, said Jennifer Young, a spokeswoman for Akron-based FirstEnergy.
She said: "There was no malicious intent that we are aware of.
"It definitely doesn't meet the professionalism we expect from out contractors and our employees."
No laws were broken, as the incident was not a security breach, and no criminal charges can be filed. However the workers will no longer be allowed on FirstEnergy projects, according to Young.
Three of the five goldfish were never found, instead believed to have been thrown away during a cleanup at the plant.
