Police have offered a £10,000 reward to help trace an Abbey Wood pensioner who has been missing for six months - during a fresh appeal for information on his 89th birthday (April 21).

Brian Smart was last seen at his home at about 7.30pm on September 22 last year but despite an extensive police investigation, there has been no trace of him since.

His devastated family have made emotional appeals for his return but, as yet, there have been no clues to his whereabouts.

Mr Smart is described as a white man, 5ft 7inches tall and of medium build. At the time of his disappearance he was generally fit and well for his age.

He walks with a stick and it was not thought he had money or an Oyster Card with him.

At the time of his disappearance he was believed to be wearing a beige or cream jacket which is featured in the CCTV footage taken at Bluewater shopping centre the day before he went missing.

He is also known to frequent Bexleyheath, Dartford and Bostall Woods in Greenwich.

Detective Chief Inspector Mike Balcombe, of Greenwich Missing Persons Unit, said: "Since his disappearance, officers have been working tirelessly to find Brian - this work has involved scouring CCTV and using specialist search teams including dog units and the police helicopter to search areas.

"We have previously released images of a watch, a mobile phone and a jacket similar to those that Brian would have had on him when he was last seen, in the hope that someone may have found them discarded or possibly been offered them for sale.
