Fingerprint technology invented in Wiltshire has been shared with a police force abroad.
The invention is helping police internationally
Esther Neate, a senior officer in the Wiltshire Constabulary, has travelled to South Africa to train 20 police officers on her product.
Ms Neate developed an all-in-one fingerprint enhancement workstation that uses special lighting.
The product was launched worldwide in 1998 and the South African police force are the latest to introduce it.
It costs around £30,000 to install the software and train officers.
Ms Neate, the force's senior fingerprint development officer, aimed to improve on older models that use conventional photography.
The machine can also clean up an image by removing any background interference.
In February of this year, three men from Swindon were convicted of drug dealing after their prints on bank notes were enhanced on Ms Neate's invention.
It was introduced jointly by Wiltshire Constabulary and Mason Vactron manufacturers.
