Vigilance brings fall in crimes.
Figures released by West Midlands Police showed a 13 per cent drop in offences between October 30 and November 6 compared with the same period in 2006.
Offences of house burglary dropped by 6 per cent, criminal damage to vehicles was down 19 per cent and serious assaults in a public place fell by more than 17 per cent.
Operation Serene encouraged members of the public to protect themselves and their property.
Superintendent Chris McKeogh said: "We know that a combination of the clocks going back followed by Halloween and Bonfire Night means a spike in crime...We hoped that by mounting an awareness-raising campaign, we could encourage people to continue to be vigilant."
