The detective's name is Captain Haddock, which is possibly a sly reference to Hergé's character of the same name from the Tintin graphic novels.
The detective, named Captain Haddock, is based on Reed Hadley's character Captain Braddock from the TV series Racket Squad (1950).
This would be Buzz Buzzard's last appearance in a Woody Woodpecker cartoon up until Tumble Weed Greed (1969). He would eventually be replaced as Woody's main foil by Dapper Denver Dooley and Gabby Gator.
