The search for a missing 73-year-old from Norwich continues as police deliver 2,000 leaflets around the city.

David Ryan went missing from his home in Crome Road on December 29 at 10.50am and police are increasingly concerned for his welfare.

Officers have distributed more than 2,000 leaflets to locals and businesses near David's home in the city centre, Magdalen Street, Anglia Square, Silver Road and Chapelfield Gardens.

Inspector Terri Cooper-Barnes said: "We know from those who knew him that he didn’t tend to travel outside of the area.

"We hope that by posting the leaflets we may jog someone’s memory if they may have seen him or remember the distinctive clothing he was wearing.”

In a statement, David's family said: "We are concerned for David’s welfare, he is someone who tends to stick to the same places in Norwich and it would be unusual for him to travel outside the county.

"His clothing is fairly distinctive and would appeal to anyone who may have seen him to get in touch"

Anyone with information or who knows of his whereabouts should contact Norfolk Constabulary immediately on 101 quoting incident number 180 of January 1.
