It has been stolen, the thief has stolen the UP tracking device from a Toronto home, police say.
The thief has left behind a small metal plate with the words UP tracking and a link to an eBay auction.
The item was posted for $10,000 on Wednesday, police said.
It is unclear who has stolen it, but the Toronto Police Service said the thief is not affiliated with the Toronto Maple Leafs.
The tracker is a wireless transmitter, and is typically worn on the wrist or ankle.
It connects to a phone via Bluetooth, and records data when the phone is connected to a mobile broadband network.
The phone then sends that data to the device, which is connected through Bluetooth.
Police said the tracker has been on the wrong side of the street for some time.
“The tracking device was stolen from a residence on East Queen Street,” Toronto police tweeted.
“The owner of the property is a known offender.”
Police did not elaborate on the details of the theft.
