Two unique custom-framed mountain bikes have been stolen from a house in Plymouth. Burglars raided the home in Downham Gardens, Tamerton Foliot, some time between September 1 and 8, possibly during the early hours of the morning. Police are now appealing for information about the bikes which were stolen and are worth £3,000. The bikes have been built to a specification and are said to be distinctive in appearance with both branded On-One. Anyone who has been offered the bikes for sale or has information about the burglary can contact police on 101.
