Officer Barbrady is a police officer. He is extremely incompetent at his job, usually being incapable of solving the crimes he is legally obliged to investigate.
For the first six seasons,Officer Barbrady was the only Police Officer in South Park, as shown in "Chickenlover". However, during the seventh season, Sergeant Yates and several other officers were added, starting in "Lil' Crime Stoppers" and Officer Barbrady became the Police Chief. Since then, he has appeared in the background. .
