Another warning to pensioners to be more careful has gone out after a 78-year-old woman was robbed by bogus officials.

The woman let the two smartly-dressed men, who claimed to be from the water board, in to her home in the Box Hill area of Abingdon.

While one claimed he was inspecting a water meter the other went through her belongings and stole 10 and her pension book.

Abingdon police are investigating the incident.
