Police are appealing for information after a bike was stolen from the cycle rack at The Mounts car park in Northampton.
The cycle racks are against the wall of the courts, close to the pay and display machine.
The owner left the bike at 7.55am on Wednesday, 2 July but when he returned at 3.15pm on the same day, the lock had been cut and the bike stolen.
It is a British racing green Raleigh, with a rack fitted at the back and a trailer attachment.
Anyone with any information about the stolen bike is asked to call Northamptonshire Police on 101. Alternatively, they can call Crimestoppers on 0800 555111.
