Lego Set ID for white curved pieces with blue Police stickers?

Question

I got another police set but can't find directions.

Answer 1

The parts with "Polizei" are from the 7741 Police Helicopter set.

Other parts are from the 7286 Prisoner Transport set (parts with "Police" and "03").

The license plate is from the Fire Truck of the 7206 Fire Helicopter set.
