A suspicious person report system includes: a biometric sensor detecting biometric data of a person in a first region； a presuming unit calculating, from the biometric data, a stress index and presuming that the person is a suspicious person when the calculated stress index is higher than a reference value； a first camera acquiring first image data of the person in the first region； a second camera acquiring second image data of the person in a second region, the second region being a route after the first region before a third region； a monitoring unit checking the second image data with the first image data corresponding to the suspicious person to thereby track the suspicious person in the second region and determine whether the suspicious person enters the third region； and a warning unit emitting a warning when the monitoring unit determines that the suspicious person enters the third region.
