Watch how Northamptonshire Police 'digi-dog' helps solve crimes

A police "digi-dog" who can detect mobile phones and laptops has been a success in her first year, according to its force.

Rosie, who works for Northamptonshire Police, is also trained to locate memory cards and even cryptocurrency.

She has found crucial evidence in cases involving robbery, drugs, domestic violence and sexual assaults.

Her handler said that watching her retrieve something that officers could not find is "an incredible feeling"."
