Licensed under the Open Government Licence v3.0.',

detail:
'Client-side heatmap of street-level crimes published by police.uk over the most recent months. Police.uk coordinates are anonymised snap-to-grid points, not exact offence locations, so the heatmap should be read as an approximation of relative density rather than a precise map of incidents.',
