Tracking dog that can smell USB sticks involved in Nelson M. arrest in Mexico | Abroad

The tracking dog in question, Hidu, is trained to detect trifenylfosfineoxide, a special coating used for USB sticks and other data carriers. These specially trained sniffer dogs can recognize very small amounts of the coating, even when many other scents are involved.

M. spoke openly online about his pedo activism, so Free a Girl quickly caught his eye. Together with American colleagues from Operation Underground Railroad, they tried to lure M. into a trap, and with success. Police arrested him at a gas station. He had a gun and cocaine on him. In the search that was subsequently carried out, Hidu’s nose was of great importance.

Because Hidu discovered several data carriers and telephones in Nelson M.’s apartment, including in a load of extremely dirty laundry and behind paintings. A total of 4 terabytes of child pornography were found.

The arrest of M. was a joint action by the Mexican judiciary, Dutch and international children’s rights organizations. M. was previously known as a member of the banned pedo association Martijn.
