Sergeant Sam Young explains: "Wildlife forms an important part of our natural heritage. Birds of prey are protected by law within the Wildlife (NI) Order 1985 and are afforded the highest level of wildlife protection.
"Anyone with information regarding the persecution of protected wildlife should come forward as doing so will help make sure those responsible go before the courts."
Claire Ferry, Conservation Officer at the RSPB said "The peregrine falcon is a native bird of prey, and is protected by European and national law. Unfortunately the peregrine population in Northern Ireland has declined in recent years, and we believe this is linked to persecution although no convictions have been secured to date. We hope people will join us in condemning any illegal activity, and that we can secure the future for this iconic bird of our skies."
If you have information in relation to illegal activity of this nature please contact police on 0845 600 8000.
