The mystery beaver's appearance in Gunnislake, South East Cornwall, could mean more beavers are living wild in the area and breeding.
Igor was one of three giant rodents to have escaped from their home in Lifton, Devon, in 2008.
The two females were caught soon after but the male eluded his captors, leaving a trail of destruction in his wake as he gnawed through trees.
So when a male beaver was found in a Gunnislake slurry pit it seemed the fugitive beaver had finally been caught.
However, it now appears that this beaver is not Igor.
