Burbridge said the unit's members were planning to kill some of the 178 prisoners held there.
Iraqi officials said the unit had become a "criminal enterprise."
British forces backed by tanks surrounded the station in the early hours of the morning, and then, joined by Iraqi troops, the combined force took control of the police station and detained an unspecified number of policemen inside.
British troops have already transferred some of the prisoners to other holding facilities.
Parts of the police station were demolished, British forces said, so it could not again be used by criminal elements.
