Crimestoppers offers a reward of up to £1,000 to anyone who calls the charity to report criminal behaviour if the information leads to an arrest and charge.
Regional police forces often mount anti-drink drive campaigns which highlight the above fact. For example, Derbyshire Police's campaign (ran throughout December 2011) resulted in 28 people calling Crimestoppers to shop a drink-driver, but every caller declined the offer of a reward. Ten people called the charity during the 2010 campaign. A decade ago the maximum reward was £500.
