Police are issuing a warning for them to be aware when making drops so they don’t become victims of crime.
The crimes have been concentrated in the north of Hull in the area bordered by Cottingham Road, Cottingham, Thorpe Park Road and Thomas Clarkson Way.
Two were of robbery, three were theft from a vehicle, and six were the unauthorised taking of a vehicle.
Some offences involve delivery drivers working for retail stores, usually in marked up vans, having property stolen from their unattended and often insecure vehicles. We believe that some of these vans are being followed and targeted because of the company livery on the side.
Some were when drivers left their vans with the keys still in the ignition and the engine running while delivering to an address.
The two robberies involved drivers being threatened for money or their vehicles.
A map of where the offences were committed is below.
Detective Inspector Allison Sweeting from Hull CID, said: “Please be aware when making deliveries and make sure your vehicle is secure, as well as the goods that you’re carrying.
“You don’t know who is watching you while you work. It’s coming up to a busy period for delivery drivers and we don’t want you, your company or who you’re working for to fall victim to these criminals.
“Please be vigilant, look out for what is around you, and please report anything to us that you may be suspicious of.
“If you have any information call 101 or if you want to remain anonymous call the independent charity Crimestoppers on 0800 55 111.”
