A Detroit police pilot project is using a gunfire detection system to help officers pinpoint where shots are being fired in the city.

Police Chief James Craig tells The Detroit News that since the program began Sept. 22 the ShotSpotter system detected what appeared to be 24 shootings. Craig says testing is being done on the system and "tweaking" needs to be done.

Craig didn't specify where the system is being tested, how many sensors are employed or how long the pilot program will last.

The technology is used by other departments, including police in Flint and Saginaw. Detroit tried to install the technology in 2011 when former Mayor Dave Bing pushed for the city to sign a three-year, $2.6 million contract, but City Council rejected the plan.
