Police are warning motorists about an upsurge in car crime.

Officers are currently dealing with a number of thefts from vehicles in the Ampthill and Biggleswade areas.

And some drivers are making life too easy for villains, said Insp Chris Sapsford.

Property taken includes items like handbags and mobile telephones that were left in full view, meaning offenders simply smashed windows to get them.

Insp Sapsford said: "With the summer holidays here, and more people heading for local beautyspots, I would like to appeal to motorists remove all valuables from vehicles, including satellite navigation systems, telephones and coats.

"It may seem like an inconvenience, but it is a lot less inconvenient than returning to your vehicle to find the windows in pieces and having to claim on insurance and arrange repairs."

Insp Sapsford also wants motorists to be aware that, because of the increase in scrap metal prices, some thieves are targeting catalytic converters, with three going in a 24-hour period.

Although it is a difficult offence to protect vehicles against, drivers are advised to use a garage at night, if possible, or ensure features such as vehicle alarms and driveway security lights are in good working order. If you must park in the road, try to choose a well-lit, busy spot.

Be suspicious of anyone working under a vehicle at unusual times of night and take a note of the registration numbers of any associated vehicles. Those in the trade can help by contacting police about anyone trying to sell catalytic converters in unusual circumstances.

Insp Sapsford said: "Police are doing all they can to apprehend offenders, but motorists can help by thinking about the security of their valuables and their vehicles and contacting us if they see anything suspicious."

Anyone with information about theft from vehicles can contact police, in confidence, on 01234 841212 or Crimestoppers, anonymously, on 0800 555111.
