Police officers have paid tribute to "one of the best" - a police dog who racked up more than 200 arrests in one year.
Former Avon and Somerset police dog Roo died in his owner's arms on Wednesday.
Roo received a commendation for his outstanding arrest rate after detaining 202 suspects at the age of five.
He retired four years ago after a six-year career with Avon and Somerset Police, where he was responsible for more than 70 percent of canine catches.
Roo's handler, Pc Jim Hampson, said: "Roo was an absolutely brilliant police dog - the perfect partner. He was totally driven and exceptionally brave - saving my life on more than one occasion. He became a bit of a legend in the force."
Inspector Andy Roebuck, who is in charge of the force's dog unit, said: "Police dogs are vital to operational policing and are extremely effective in a wide range of situations from searching, detecting people, drugs or explosives to crowd control and detaining criminals.
"Not every dog we start training makes it through to become an operational dog, it takes a lot and Roo was one of the best."
Roo retired in December 2009 and went to live with a friend of Pc Hampson, who visited him regularly.
