PoliceAPI

The Police API allows you to retrieve information about neighbourhood areas in all 43 English & Welsh police forces. All forces are required to keep this data accurate and up to date, so the API provides a rich and definitive data source for information such as:

Neighbourhood team members
Upcoming events
Crime levels & statistics
Nearest police stations

The API is implemented as a standard XML REST web service using HTTP GET/POST requests.

Far from perfect, but a move in the right direction see Icons passim.
