Nashville (AP) -- FBI Data shows that violent crime in Chattanooga did not drop by 50 percent while Bob Corker was mayor, as he claims in a new campaign ad.
Republican US Senate Candidate Bob Corker uses the figure in a new television commercial with his mother, Jean.
The FBI's annual report shows violent crime in Chattanooga did drop between 2001 and 2004, but only by 28.7 percent.
That report draws its data from local and state authorities and is considered the most comprehensive source of crime data.
Information released by Corker's campaign Thursday showed that the 50 percent figure was based on preliminary statistical data for 2004.
Chattanooga Police spokesman Tetzell Tillery said the discrepancy may stem from differences in how the local police and the FBI classified certain kinds of crime.
