Police are looking for a man with links to the Uckfield area who failed to appear in court earlier this year on a charge of causing or inciting a girl under 16 to engage with sexual activity in Heathfield.
Police say that Dunham, a landscape gardener, whose last known address was in Albert parade, Eastbourne, also has links with the Uckfield area.
He is described as white five, feet ten inches tall, of medium build with green eyes and short brown hair.
Anyone who sees Dunham, or knows where he may be, is asked to contact Sussex Police on 101 or email firstname.lastname@example.org. You can also call the independent charity Crimestoppers on 0800 555 111.
