The search for a missing man from Hove has switched to Kent after his car was found in Sevenoaks.
Keith Miller, 42, was last seen in Hove on Monday 29 March.
Police are concerned for his health because he has a mental health condition and is unlikely to have been taking the medication that he needs.
Mr Miller owns a red Landrover, registration F236UBJ.
Sussex Police said that it was found yesterday in Avenue Road, Sevenoaks, near Knole Park.
It was parked and secure and there were signs that someone had been living inside it. Officers believe that the vehicle has been in the Sevenoaks area since Saturday 3 April and that Mr Miller may also be in or around the Sevenoaks area.
Mr Miller likes the countryside, seaside areas, and areas with trees. He regularly takes walks in the countryside and has also stayed at hotels in the past.
He had been living in London W9, but had been in the Hove area for some days before his disappearance.
He is described as white, 5ft 10in tall, with short, straight fair hair, a pale complexion and brown eyes.
He was last seen wearing jeans and a t-shirt and was clean shaven.
Sussex Police issued an appeal for anyone with information which could help police to find Mr Miller to make sure that he is safe and well to call 0845 6070999.
