 Since the 1990s, there has been a marked decline in crowd trouble at matches, as a result of stricter policing, CCTV in grounds and the advent of all-seater stadia. In 2007, the club launched the 'Back to the Shed' campaign to improve the atmosphere at home matches, with notable success. According to Home Office statistics, 126 Chelsea fans were arrested for football-related offences during the 2009 – 10 season, the third highest in the division, and 27 banning orders were issued, the fifth-highest in the division.
