Olivier Rukundo, 33, was arrested on April 30, in Byimana sector, Mpande cell with 37 kilograms of cassiterite and coltan minerals.
Chief Inspector of Police (CIP) Sylvestre Twajamahoro, the Police spokesperson for the Southern region, said that Rukundo was "mining, buying and selling minerals illegally."
"Police had information that Rukundo heads a group of illegal miners, and use the cover of the night to mine cassiterite and coltan in Kanyarira," said CIP Twajamahoro.
He added: "Licensed mining companies in the area had also reported Rukundo as the main character in the area, who carries out illegal mineral trade and in most cases buying them from their casual employees.
On Thursday, we had credible information that he had brought a new consignment. When Police searched his house, they recovered 37kgs of casetirite and coltan, and he was immediately taken into custody."
Rukundo admitted to the crime saying that he was using other people to enter in the concessions at night but also conniving with casual miners of the firm to steal and bring the minerals to him.
CIP Twajamahoro said that illegal mining activities in this area were contributing largely to environmental degradation and affecting legal mineral business especially for the licensed owners of the concession.
He warned residents against such unlawful acts and urged them to report those who break the law.
