Technically that bike still belongs to the Royal Mail, it should have been handed back to the stores to be disposed of.
But having been responsible for servicing RM bikes. Many were not, and kept by posties, ineffective management overlooked the issue.
Several hundred had been taken out of use and dumped round the back of the RM depot in Crow Lane, Northampton.
Rather carelessly they were in full view of an adjacent footpath and one night some sticky fingered herberts used a car jack to open up the pallissde fencing enough to get inside and steal a couple of dozen of them.
No records were kept re serial numbers or the like, and they didn't even know for sure how many were there in the first place so they could only guess how many had been stolen and had no way of identifying individual bikes if they ever came to light.
With no CCTV, no witnesses, no useful evidence at the scene, and no means ID'ing the bikes, that investigation was closed and filed before it began.
