There are further cases mentioned in the article from other police forces.
- South Yorkshire Police used it to find a 65-year-old man who became trapped after falling down a railway embankment in Sheffield.
- North Yorkshire Fire and Rescue Service found a woman who had crashed her car but was unsure where she was.
- Humberside Police were able to quickly resolve a hostage situation after the victim was able to tell officers exactly where she was being held.
If these are all completely made up, and have made it past the BBC, then I'm rather surprised.
EDIT: I think this must be the incident: https://www.hulldailymail.co.uk/news/hull-east-yorkshire-new...
(The report mentions a substantial search, and in particular commends the actions of good doggo PD Logan: https://twitter.com/HPDogSection/status/1103713458334416896)
