A Ferrari racing car has been stolen from Hethersett near Norwich.
The black Ferrari 430, worth £170,000, was in a trailer in a hotel car park on Norwich Road. It was taken just before 8.30pm on 8 November.
Police say it was towed away by a long wheel base white Mercedes Sprinter van.
The Ferrari was produced as a race car for the GT3 series. It is not a road car and cannot be converted into one.
Officers want to speak to anyone who may have seen the trailer, or has any information about where it and the Ferrari are now.
