McDonald's restaurants in Europe and Australia are using DNA spray to catch thieves. The device is installed above the entrances and is activated by staff members during robberies. The offender is sprayed with a DNA solution as they exit the building. The solution stays on clothes and skin for several weeks and is invisible to the naked eye. With a UV light, police can find the marking and link a suspect to a particular crime.
