Wildlife officers asked Yellowknife residents for help after discovering the remains of a bear in a ditch off Highway 3 to the west of the city on Friday.
In a statement posted online, the territory's Department of Environment and Natural Resources (ENR) asked residents to help officers find the person responsible for the bear's fate.
According to ENR, the bear – found in a ditch 12 km outside Yellowknife – had been "heavily scavenged by birds and other wildlife" since its death.
"The bear was wrapped in a tan-coloured canvas tarp with a red dog leash around its neck," ENR's statement read.
"ENR is seeking the public’s assistance to locate the person or people responsible.
"Under the Wildlife Act, it is illegal to waste, destroy, or abandon a wild animal such as a black bear."
Anyone who can help officers with information about the incident should contact ENR's North Slave regional office at 867-767-9238, extension 53258. A toll-free alternative is available: 866-762-2437.
