A Nottinghamshire Police dog is back on the beat after being stabbed in the line of duty earlier this year.
In fact he has helped make a string of arrests possible.
PD Quantum was stabbed a number of times in March while apprehending suspects during an incident in Top Valley, Nottingham, in which three police officers were also injured.
On 14 July he showed he was fully recovered when he assisted in the arrest of five people in connection with a theft, assault and a number of reports of criminal damage in Sutton-in-Ashfield.
PD Quantum, a two-year-old Belgian Malinois-German Shepherd cross, was deployed after the report came in to Nottinghamshire Police early on Saturday morning.
He helped to track one suspect to some nearby bushes.
A spokesperson for Nottinghamshire Police said:
The victim of the assault, a 36-year old man, has been taken to hospital for treatment for his injuries, which aren’t believed to be life-threatening or life-altering.
PD Quantum, who required nine stitches after the incident, is just one of a number of police and service dogs to be injured in the line of duty recently.
Seven-year-old Axle was attacked while officers from Derbyshire Police attended a domestic incident on High Street, Riddings, on 4 July this year.
He has since been discharged from the veterinary centre where he was recovering and is back with his handler, PC Dean Allen.
Just two days after Axle was stabbed a Bill giving greater protection to police animals came a step closer to becoming law.
The Animal Welfare (Service Animals) Bill passed unopposed at its second reading in Parliament on 6 July.
It aims to remove a section of the current law of self-defence often used by those who injure a service animal.
