Abstract
The invention relates to an apparatus for and a method of detecting latent fingerprints on a previously heated substrate, such as a bullet casing following discharge of a bullet. By applying a potential difference across the substrate, and contacting the substrate with detection means, such as graphite coated beads, arranged to selectively attract to or repel from the area of a latent fingerprint on the surface, a latent fingerprint may be recovered.
