Police are trying to trace a bike stolen from a shed in Welwyn Garden City.

A ladies’ blue Giant Anthem X mountain bike with a size 29 frame was taken sometime between 8pm on Tuesday March 11 and 8am Wednesday, March 12 from a property in Tempsford.

The bike also has a white seat, black bottle cage and deep chip out of the paintwork on the frame.

PC Paul Edmondson is investigating and said: “This bike is quite distinctive and I would like to hear from anyone who knows of the bike’s whereabouts or has been offered a bike of a similar description for sale recently.

“If anyone remembers seeing anything unusual or suspicious between the stated times please contact me as you may have information that can assist the investigation.”

Anyone with information is asked to contact PC Edmondson via Hertfordshire Constabulary’s non-emergency number 101, citing crime reference B1/14/699. Alternatively call Crimestoppers, the independent charity, anonymously on 0800 555 111.

There are some very simple things you can do to deter opportunist thieves from stealing your bike:

* Mark the frame of your bike with your postcode using a UV pen or contact your local cycle shop, as most will mark them for a small cost. You can contact your local Safer Neighbourhood Team for advice on other property marking initiatives available on 101.

* Register your bike, including the frame number, on www.immobilise.com, a free online property database which police use to check stolen property. That way, if your bike does get stolen, you have more chance of it being returned to you.

* Never leave your bike unlocked – even if you’re just popping into the newsagents.

* The best kind of lock is a quality solid steel D-shaped shackle lock. You can buy these at any bike shop.

* Always lock your bike to something solid like a lamp-post or railings, preferably in a public area.

* If you have quick release wheels, take off the front wheel and lock it to the frame and back wheel.

* If you have a pump or detachable lights take them with you when you leave your bike.

* Make sure you have adequate insurance cover for your bike.
