Robert Guthrie, 39, is wanted on prison recall, but has been evading arrest for a number of weeks.
Searches are ongoing at various associated addresses and it is believed that Guthrie may be living a transient lifestyle in a bid to remain under the radar.
Police are now asking for the public to come forward and assist in their search for him – by passing on any information about his whereabouts or where he may be residing.
It is a criminal offence to harbour a wanted fugitive and anybody found to have done so could face a potential prison sentence themselves.
