Police in Grantham have urged bike owners to remember to take steps to ensure their bicycles are safe after a recent spate of thefts.
Making sure your bike is locked up overnight, even if it is in your back garden, means potential thieves cannot simply wheel it away from your property.
If you pop into a house or shop and leave your bike outside, even if it is only for a minute, remember to padlock your cycle to a nearby sturdy construction such as a lamppost or railing so it is not easy to steal.
Officers would like to hear from anyone who saw or thinks they might have witnessed a bike being stolen, or anyone who knows where the bikes are going.
Anyone with any information is asked to call 101 and report what information they have, or alternatively contact the independent charity Crimestoppers anonymously on 0800 555 111.
