Basil "Baz" Bailey was the leader of a gang at Coal Hill School in the 1990s. He was a tall, red-haired, skinny young man who wore black jeans, a black T-shirt and a black padded jacket.

Baz and his gang dealt in illicit drugs. When he planned to move onto more powerful drugs, such as crack cocaine, Sam Jones reported him to the police. They found none on him and he was released. He obtained cocaine from Machete Charlie on credit and tried to force Sam to take the drug so she would be addicted to it. They chased her to Foreman's Yard, where they encountered the Eighth Doctor. The gang attacked the Doctor, who quickly knocked them down. They fled and the police found the drugs when they arrested the Doctor.

Baz feared Charlie's retribution if he was not paid, so he plotted to retrieve the drugs. He paid locals to cause a riot at Coal Hill Police Station. The gang escaped in the confusion, but the Doctor took the drugs and ran away. They pursued him to Foreman's Yard, where the Doctor escaped in his TARDIS. Baz pulled a knife on Sam, who was also present, but the Doctor returned moments later and gave the drugs back to Baz, who was then arrested by the arriving police. (PROSE: The Eight Doctors)
