Police in the Netherlands are to use rats to help them solve crimes by having them sniff out gunshot residues.
Five brown rats named after famous fictional detectives - including Hercule Poirot and Magnum - have been showing off their skills at a training centre in Rotterdam.
The BBC reports they will initially be deployed after shootings to identify people who have used guns. Police said their accuracy is remarkable and they could also be used to detect drugs, money, bodies or blood.
