POLICE hunting a former RAF serviceman who vanished from his city home have carried out a search in the grounds of Lauriston Castle as fears grow over his safety.
Alan Goulden, 64, who is diabetic, was last seen in the Maybury Road area five days ago and left his supply of insulin in his house nearby.
Police dogs and horses were used alongside eight officers to search around the castle grounds in Cramond yesterday, but they found no sign of Mr Goulden.
Mr Goulden was known to visit the scenic spot while walking his dog and relatives thought he might have gone there after he was last seen between 6.30am and 7.30am on Saturday.
Officers have been combing CCTV footage from the Maybury area, but are yet to find any shots of Mr Goulden.
Posters featuring his photograph are being displayed by local shops and businesses and police are planning to question motorists and pedestrians on Saturday.
A police helicopter was called out on Saturday after he vanished. It is believed Mr Goulden may have visited a supermarket at the Gyle shopping centre around 8am that morning.
Sergeant Jason Gilkison, part of the inquiry team based at Corstorphine police station, said: "We've been working closely with British Transport Police to search railway lines in the Maybury area as he frequented them to walk his dog.
"We are concerned for his wellbeing because he is diabetic and didn't have his insulin with him.
"We are still very optimistic we can trace him and a team of eight officers are working directly on the inquiry."
Police are monitoring his bank accounts to see if any money is withdrawn, but since his disappearance they have remained untouched.
Mr Goulden lives with his partner and also has other relatives in the Capital. He left the RAF around 30 years ago and currently works at a city packaging plant.
He is described as white, 5ft 7in to 5ft 8in tall, medium build, with a ruddy/red complexion and short, light brown hair. He was believed to wearing a navy blue Nordic make waist length jacket, light blue jumper, checked shirt, trousers and brown leather shoes. He is well-spoken with an English accent.
Mr Goulden is well-known in the Maybury area for walking his small white Papillion dog, but does not have the dog with him.
