Some of the violence was trimmed to get an "R" rating, most notably the police station massacre. This scene appears in its entirely in a flashback sequence in Maniac Cop 3 (which was also originally given an "NC-17" rating).
Although the UK cinema version was uncut, the video release was cut by 4 seconds by the BBFC to remove shots from the flashback shower murder in the prison, repeated from the original film. The Medusa DVD features the cut video print.
The Swedish VHS version is cut to reduce the machine gun massacre at the police station.
