Police are urging motorists to be vigilant after a single night saw seven thefts from cars in Letchworth, with sat navs, cash and other items taken.

One incident, which took place between 5pm on Monday, May 9, and 7am the following day, concerned a blue Audi A4 which was left parked on a driveway in Station Road. Someone gained access and took a sat nav, CDs and a bluetooth headset.

Another, at about 3am on the Tuesday morning, saw someone enter a gold Ford Galaxy, which had been left unlocked on a driveway in Pixmore Avenue, and take a sat nav, coins and a phone charger.

A third concerned a Mini One, left parked in Broughton Hill. Between midnight and 6am on the Tuesday morning someone entered through the unlocked boot and took a sat nav and coins from inside.

Between 11.15pm and 8.15am, someone entered a grey Land Rover Freelander parked in Glebe Road and took the sat nav.

A sat nav was also taken from a silver Vauxhall Astra, parked on a driveway in Baldock Road, between 6.30pm on May 9 and 7am the next day.

Another incident, between 7pm on the Monday and 9am on the Tuesday, saw a sat nav and CDs taken from a red Vauxhall Corsa in School Walk.

Between 9am on the Monday and 8.10pm on the Tuesday, someone took an iPod and sunglasses from a Volkswagen Gold parked on a driveway in Ridge Road.

Finally, between 5.30pm on the Monday and 8.30am on the Tuesday, someone entered another vehicle in Ridge Road and searched inside, but left without taking anything.

There was also one further attempted theft from a vehicle in Ridge Road over the night of Monday, May 9, and Tuesday, May 10.

Sgt Alan Clarke, from the Letchworth and Baldock safer neighbourhood team, said: “Additional night-time patrols are being carried out to help catch these offenders but we need motorists to remain vigilant and report any suspicious activity to police immediately.

“I’d also like to take this opportunity to remind motorists to remove any valuables from their vehicles when leaving them parked and to ensure vehicles are properly locked.

“Don’t just rely on your key fob and the sound of the locks engaging, make sure the doors and boot are locked by double checking them by hand.”
