Seven cars have been stolen during an overnight spate of thefts in Hertfordshire.

The offences took place between last night (Monday, February 12) and this morning (Tuesday, February 13).

Three vehicles were stolen from Leverstock Green, with an additional four taken from Hertsmere.

Hertfordshire police have appealed for witnesses to come forward.

Leverstock Green

Overnight in Leverstock Green, three keyless vehicles were taken.

A Land Rover was taken from Tike Kiln Crescent (crime reference 41/12430/24), a Volvo XC90 was taken from Kiln Ground (crime reference 41/12440/24) and a BMW X5 was taken from Fir Tree Close (crime reference 41/12425/24).

Detective Sergeant Yolanda Morales-Willis, from the Dacorum Local Crime Unit, said: “We’re carrying out enquiries to establish the circumstances around the thefts and to try and identify those involved.

“If you have any information which may assist us or have captured anything of note on doorbell cameras, dash cams or CCTV systems, please get in touch."

Hertsmere

Four keyless vehicles have been reported as stolen from Borehamwood and Potters Bar, including two Jaguars, a Range Rover and a Ford Focus.

Hertsmere Chief Inspector Mark Bilsdon said: “We’re carrying out enquiries to establish the circumstances around the thefts and to try and identify those involved.

“We’ll be increasing our patrols, but we cannot be everywhere at once and would urge people to please review the security of their vehicles, especially ones which are keyless.”

Hertfordshire police advice

Hertfordshire Constabulary have released the following advice for owners of keyless vehicles: "Keyless vehicles are often targeted by criminals using signal relay equipment, which can pick up the fob’s signal from outside a home and use it to unlock and start vehicles without physically having the key.

"Using a signal blocking pouch, such as a Faraday bag, or storing your key fob and any spare keys in a metal box can help prevent the equipment from working effectively.

"If you can, turn off the wireless signals on your fob when not in use and ensure that keys are kept as far away from vehicles as possible.

"If your vehicle has a tracker, make sure it is activated.

"You could also consider concealing a small ‘tracking tag’ inside your vehicle to help trace it should it go missing.

"If you witness any suspicious activity around cars, vans or motorcycles, please call 999 straight away.
