A 20-year-old man had his wallet stolen by a group of robbers, one of whom was wearing a skeleton mask.
This took place between 6.30pm and 6.45pm on Wednesday, December 6 at the junction of Burnside and Olive Close.
The victim was approached by a group of males aged between 16 and 19, who were wearing dark clothing with their hoods up.
All of them were wearing masks, including one in a skeleton style, except for one who was described as black, medium build, around 5ft 10in, and wearing a dark puffa jacket and possibly black Air Force 1 or Air Max trainers.
Anyone with any information should contact Herts police via 101, quoting crime reference F1/17/5884.
There have been several robberies in the district recently, and two teenagers were arrested after robberies in Harpenden in October.
A woman was also robbed near Hill End Lane by two masked men last month.
