Police are appealing for witnesses after a delivery driver was robbed at knife point on Saturday.
At just before 9.10am, the victim was in Main Road North, Dagnall, near Berkhamsted when he was approached by three men wearing balaclavas.
They threatened the victim with a knife and stole a number of parcels from the van.
The offenders then left the scene in a vehicle.
The victim, a man aged in his fifties, was not injured during the incident.
The offenders were all wearing black clothing and balaclavas, and so no further description is currently available.
Investigating officer Detective Sergeant Katherine Peacock said: “This was an extremely frightening ordeal for the victim, who was going about his work delivering parcels.
“Thankfully he was not injured, but a number of parcels have been stolen from the van, which is a DPD courier van.
“I am appealing to anybody who was in the area and believes they may have witnessed this incident to please get in touch with Thames Valley Police.
“I would particularly like to hear from anybody who was driving in the area and who may have dash-cam which has captured the incident to contact us, along with anyone with CCTV or doorbell footage.
“You can make a report via our website or by calling 101, quoting reference 43240454580.
“Alternatively, for 100% anonymity, you can also call the independent charity Crimestoppers on 0800 555 111.”
