Police confirmed he had allegedly been involved in an "altercation with a man and his dog" earlier. They were told the man had bitten the animal.
Four men arrested on suspicion of manslaughter have been bailed.
A police spokesman said the man had been involved in an "alleged altercation" with a 45-year-old man and his dog.
A man, aged 45, initially arrested on suspicion of causing grievous bodily harm was released without further action on Tuesday.
