Detectives based in Busia county arrested a foreigner with 50 pieces of elephant tusks.
The tusks and the 85 pieces of wildlife bones confiscated are believed to have been smuggled from a neighbouring country.
Joseph Ndenda is placed in police custody awaiting arraignment for the offence of possession of wildlife trophies without a permit.
Five men were arraigned last year in Kabarnet for alleged possession of 21 elephant tusks worth Sh7.25 million.
The suspects were Kariuki Njoroge, Joseph Riwaren, Kurkamar Lokoriara, Turu Lokoriara and Amos Kamarinyang.
They had been arrested by KWS while transporting elephant tusks of weighing 72.5kg at Ribko, Tiaty.
A 42-year-old man, David Ndegwa, was also arrested last year for being in possession of 100kg of elephant tusks worth Sh10 million.
Ndegwa was after a tip-off from the public, as police officers posing as his customers arrested him and his colleague escaped.
