Are you a modern day Sherlock Holmes?

Are you a 'Crime Cracker'?

Have you and your friends started a group or campaign to improve the quality of life on your estate or neighbourhood and succeeded in bringing down crime?

The BBC is looking for people who've taken action alongside the police in order to make a difference.

In September the BBC will showcase a day of crime reporting looking at the issues that matter to people in every part of the United Kingdom.

If you and your neighbours have become modern day Sherlock Holmes or just banded together to do simple things which have reduced crime then we'd like to hear from you.
