The Kenya Wildlife Service has been rediscovering poachers with a new detector since the last few days.
It is a kit to identify fingerprints of fingers that came into contact with ivory up to 28 days after handling. 
Mark Moseley, a specialist of the British Investigation Police, has experimented with this and made it available to the Kenyan authorities.
This is a much longer period than the two to three day period that was previously possible and thus makes it easier to recognise poachers, traders and other persons involved in illegal ivory sales, such as intermediaries who weigh, package or sell.
The kit, which Moseley developed with the help of Dr. Leon Barron of King's College in London, is currently used in Kenya, distributed by the IFAW (International Fund for Animal Welfare). 
KWS officials told the British newspaper Standard. uk that this new system is making a "huge difference" in helping to identify offenders.
Next week Moseley will receive a special prize from the International Animal Welfare Fund. 
"This research has not only had a positive impact on criminal investigations - said the expert - but has also allowed people around the world to have an additional legal tool to try and help save the animals targeted for their ivory.
