Scottish insurance broker David Gibson has made a Reggie Perrin-style disappearance, amid allegations of financial impropriety.

Gibson left his home in Stranraer at 11am on February 11 in his green Volkswagen Golf and was seen travelling on the A75 just over an hour later.

Like a scene from the 1970s comedy starring Leonard Rossiter, the church elder's car was found abandoned at Ayr on the Scottish coast on February 16. It allegedly contained farewell notes to his wife and daughters. Police searches of Ayr revealed nothing.

His wife Dorothy has urged Gibson, who is not a member of the British Insurance Brokers' Association or the Institute of Insurance Brokers, to contact a member of the family. "We're extremely worried," she said.

Dumfries police have said that plain clothes officers are treating Gibson as a missing persons case.

A police spokeswoman also confirmed that detectives were investigating Gibson's business activities.

But she would not reveal the nature of the inquiry or the veracity of newspaper reports into his disappearance.

A Scottish newspaper has reported that Gibson owes thousands to customers in Stranraer and admitted his guilt in the farewell notes.

It said that Gibson had been seen on CCTV cameras and had been recorded using his credit cards in Glasgow, Ayr and Stirling since his disappearance.

Calls to David Gibson Insurance in Stranraer go unanswered.

Gibson is described as white, about six feet tall, of slim build, with greying brown hair, green eyes, pale complexion and bushy eyebrows.

He was last seen wearing old blue jeans, a charcoal coloured jumper, purple fleece and brown brogues.
