A collection of deep-frozen human body odours is helping police dogs in eastern China track down criminals, the Xinhua news agency reports.
Some 500 odours, sampled from criminals and from different crime scenes, are stored in the scent “bank” in Nanjing.
The archived scents are then presented to police dogs for comparison with odours recovered from fresh crime scenes, the bank’s founder told Xinhua.
He said the process has so far led to the identification of 23 suspects.
