Police in Kirkwall have detained a 73-year-old man who was acting suspiciously near birds nests in Orkney on Saturday.
The force said a number of items of interest were recovered, which resulted in further enquiries being carried out.
A report has now been submitted to the Crown Office and Procurator Fiscals Service for consideration.
Inspector Alicen Winston said: “Wildlife crime and the detection and disruption of offenders is a priority for Police Scotland.
“I would like to thank the members of the public on Shapinsay who were vigilant and took action which allowed us to investigate the matters reported and deter further offences being committed.
“I would remind the public in Orkney that any suspicious activity which may suggest that wildlife crime is being committed in their area should be reported to Police Scotland on 101 or via Crimestoppers on 0800555111.
“All reports received will be thoroughly investigated.”
