Police Cruisers are always painted pearl white and are distinguishable by two strobing red lights on the engine pods. They have atmospheric capability and take off vertically. Typical crew complement is two ISSP officers. The design was similar to Faye Valentine's Red Tail.
When a prisoner ship carrying Udai Taxim is seized by its prisoners, a fleet of Police Cruisers intercept it. However Udai manages to destroy nearly all of them by detonating a section of the ship that had been jettisoned. 
The ship that Bacchus and Manley stole seems to be of a slightly different design than the cruiser shown here.
