Transport police are trying to reunite a stolen bike with its rightful owner.
Officers at Hemel Hempstead railway station arrested a 16 year old boy last month on suspicion of going equipped to steal.
The teenager had a bicycle with him and police are hoping to get it back to the owner.
PC Ian Hancox, the investigating officer, said: “We are currently working to establish where the red and black bike had come from.
“If you had a cycle taken on the day of the arrest - January 29 - or close to it, and have yet to report it to police, I would urge you to come forward.
“Bicycles remain a popular target for thieves but there are a number of ways people can help lessen their chances of becoming a victim of crime, like ensuring their property is adequately marked and secured.
“It’s also important to remember to register your bike and ensure a solid lock is used to secure it. If a bike is adequately marked, it makes it much easier to identify and therefore helps reduce the risk of theft.
”BTP officers regularly conduct cycle crime awareness surgeries at stations to offer crime prevention advice and we will continue to work closely with train companies to tackle cycle crime.”
Anyone who believes the stolen bike may be theirs can contact British Transport Police on 0800 40 50 40, quoting crime reference LNA/B7 of 06/02/2013.
