The anti-narcotic police tweeted that "in the last three years she (Sombra) became a torment of "Otoniel".
The drug lord in question is head of Clan del Golfo (the Gulf Clan) - a drug cartel which has its own guerrilla army - and he has had enough of the animal [VIDEO]'s incredible skills. It's in Turbo that Sombra sniffed out the 10 tons of cocaine.
She is now the target of Colombia's most powerful and unsafe drug cartel.
Sombra was originally posted to various ports on Colombia's Atlantic coast, where smugglers sent speedboats loaded with drugs north to the United States or across the ocean to Europe.
In a bid to protect their precious drug-busting weapon, Colombian officials have transferred Sombra from the port city of Turbo, known to police as Urabenos' stronghold, to the capital city of Bogota, where she now works at the global airport.
A real-life McGruff is taking a bite out of crime in Colombia, sniffing her way to high-profile drug busts - and now, the cartels have started taking notice. According to Rojas, Sombra has an incredible sense of smell, beyond that of other sniffer dogs.
"We are responsible for her safety, " said officer Jose Rojas, Sombra's 25-year-old handler. Sombra can be seen at work in the video below. Investigators uncovered the threat against Sombra through an intercepted phone call.
The German shepherd has already followed her nose toward a record number of drug detections, finding illicit stashes hidden in suitcases, boats and even large shipments of fruit. So to put a $70,000 price on Sombra's head shows how much the notorious gang fears one dog, police said.
According to a U.S. government report released in June, coca production- the base ingredient for the drug- rose 11 per cent in 2017, has reached an all-time high.
