Nothing Sinister Here

This is a simple three-sentence story from BBC News:
A search has again taken place in Weston Park in Bath by police investigating the discovery of three human feet. The first turned up inside the park in February, the second and third were found in nearby gardens in July and earlier this month. Police say they do not think there is anything sinister behind the finds but they are continuing to investigate why they keep appearing.
Nope, nothing sinister here. Move along. It's just three human feet found in a park.

Wait a minute. Three feet? Shouldn't you contact Scotland Yard?
