An armed masked robber held up a village betting shop escaping with hundreds of pounds.
The crook, believed to have been carrying a firearm in a white carrier bag, jumped over the counter at Ladbrokes in Kings Langley to get to the money.
At the time of the raid carried out at around 8.15pm yesterday (Thursday) there was just one lone member of staff inside the Hempstead Road shop and no customers.
Det Inps Sam Khanna said: “I would like to highlight that this type of crime is rare within Kings Langley, and for people not to be alarmed.
“The incident is subject to a thorough investigation. I am appealing to anyone who saw the suspect leaving the shop, or anyone who may have information about this crime, to get in contact as soon as possible.”
The thief is believed to have made off in a silver car.
