Inspector Neil Hubbs said: “It’s 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 becoming a victim of bike theft.
“We regularly conduct cycle crime awareness surgeries at stations across the North West to offer crime prevention advice and mark bikes. Follow our twitter account @BTPLancs for details of these events.
“We also target stations with covert and overt policing operations to catch would-be offenders in the act and CCTV provides a great tool to identify those we don’t catch red handed.
“We will continue to work closely with train operating companies to tackle cycle crime.”
