To wrestling fans, Croitoru is better known by his ring names, Johnny K-9 and Bruiser Bedlam. He competed in several Canadian wrestling promotions, including Stampede Wrestling, and later wrestled for New Japan Pro Wrestling, Smoky Mountain Wrestling, and the World Wrestling Federation (WWF). He wrestled as a jobber in the WWF, but he was booked to win titles in several other promotions.

Croitoru is also famous for his history of legal problems. He was a member of a Satan's Choice, a biker gang, and has also been convicted of assault, trafficking cocaine and bombing a police station. In 2005, Croitoru was arrested for the murder of lawyer Lynn Gilbank and her husband Fred. After a lengthy investigation, the charges were dropped in June 2006 because of insufficient evidence.
