Locals dubbed it “the friendly bear” and called it “Chipi” after the park where it lived.
The bear was captured by officials from the federal environmental protection agency (Profepa) while having a snooze in the backyard of a house after its residents alerted the authorities to their unexpected guest.
Veterinarians at the Autonomous University of Nuevo León checked it over and fitted it with a radio collar.
The animal was also castrated, a move which is now being investigated by Profepa.
The agency has released a statement saying that the decision to castrate the bear was taken by the co-ordinator for wildlife at the university after consulting with Profepa’s director-general for wildlife control, Martín Vargas Prieto.
Mr Vargas Prieto argued that the bear had to be castrated to avoid him getting into fights with other bears once he is released in the Sierra de Nido mountain range in Chihuahua state.
Both the castration and the planned move to Chihuahua have caused outrage among people in the state of Nuevo León, where the bear was captured.
