No burglaries or car crimes at all were reported in Shoreham last week - and police there are stunned.
Figures for Hove also show a dramatic fall over the same period.
The figures have been hailed as "stunning" by senior police officers in both towns.
They came after the divisional command team was praised by the Home Secretary for high-profile policing initiatives.
As well as the zero crime rate in Shoreham, there were only 12 violent crimes in Hove.
That compares with 19 for the same week last year and beats the target rate of 18.
Burglaries fell from the target rate of 19 to 15 for the week and have been as low as 12.
Car crimes were down to just 27 for the week against a target of 39.
Sergeant Steve Barry, of Hove police, said: "These figures are quite stunning. To have no burglaries or car crimes at all in Shoreham is excellent.
"It will reassure people in Shoreham and Southwick that our resources are not used mainly in Hove."
He said the continued high-visibility policing policies in the area were discouraging crime.
But the car crime reduction unit was also having a big impact by targeting known criminals.
Another four officers had also been taken on to man the area crime car, making six in all.
