A fourth man has been charged in connection with a dog fighting ring in Nashville.
Earlier this month, detectives with the Metro Nashville Police Department arrested three people and rescued 21 dogs from a home on Rowan Drive.
Eleven adult dogs and 10 puppies, all of which had varying degrees of injuries, were taken to Metro Animal Care and Control.
Specialized Investigations Division detectives discovered the dogs while executing a heroin-related search warrant.
They discovered a treadmill believed to have been used to condition the dogs, and syringes used to inject the dogs with chemicals.
"Detectives were surprised to see a number of animals with scars and open wounds," Don Aaron with Metro Police said at the time. "It's heartbreaking when you see the wounds and scars these animals have had to endure."
