Gamekeepers are being urged to remain vigilant by wildlife officers ahead of the 2014 game shooting season with the launch of the annual Operation Cockerel campaign.
Set up in 2007, Operation Cockerel aims to tackle the thefts of pheasants, poults and partridge chicks across the county.
This season, police will be stepping up patrols and vehicles transporting live birds will be subject to spot checks across the county.
The operation raises awareness of this type of crime, ensures that shoot owners and gamekeepers remain alert and encourages members of the public to report anything suspicious.
PC Jason Pegden, wildlife officer at Norfolk Police, said: “Landowners, gamekeepers, shoot owners and managers should ensure they remain vigilant at this time of year, as gaming equipment, feeders and game birds are at increased risk of theft during this busy season.
“Officers will be stopping vehicles and checking paperwork across the county as part of measures to prevent this type of crime, and we would encourage anyone to report any suspicious activity to police.
“Crimes in progress should always be reported by calling 999, information or suspicious activity should be reported on 101.”
Anyone with any information should contact PC Jason Pegden at Wells SNT on 101.
