CCTV images have been released after a bike worth £1,000 was stolen at Grimsby Town railway station.
British Transport Police have issued the pictures of a man they want to speak to in connection with the theft, which took place on Tuesday, June 17.
PC Dermott Carlin, leading the investigation, said: "The owner locked his bike in the cycle racks at the station at 11.17pm.
"When he returned 20 minutes later it was missing, and someone had cut the lock to remove it.
"The stolen bike is a black and white Scott Spirita S30 men's racing bike with flat handlebars, valued at £1,000, and the owner is understandably very keen to get his property back."
The person responsible is believed to have left the cycle racks in the direction of Grimsby town centre.
PC Carlin added: "I believe the man in the images we have released has valuable information about this theft.
"I would ask anyone who recognises him to get in contact."
Anyone with information is asked to contact British Transport Police on 0800 40 50 40, or text 61016, quoting reference PSUB/B6 of 15/07/2014. Information can also be passed anonymously to the independent charity Crimestoppers on 0800 555 111
