Dyer, who is 30 and from Leeds, was released from prison on licence in May this year after serving part of a sentence for armed robbery.
He has been recalled to prison as he has breached the terms of his release.
Dyer, who is described as being about 6ft 2ins tall and of slim build, is now featured on Crimestoppers’ Most Wanted page.
This means that a cash reward of up to £1,000 is on offer for information provided directly to Crimestoppers which leads to his arrest.
Dyer is known to have links to the Osmondthorpe and Killingbeck areas, as well as Castleford.
Officers are continuing their enquiries to locate him.
Information can be reported anonymously to the independent charity Crimestoppers on 0800 555111 or online
