A Great Dunmow man got a surprise in his Tesco finest pack of four granola squares.

Roger Wolfendale found a metal object in one last night (Wednesday). On closer examination it turned out to be a gold filling. The filling is about 1cm across.

He has raised the issue with Tesco and the Dunmow store's bakery manager today said they will investigate.

Roger said: "I googled how much a gold filling is worth - it's about £50. It's perhaps about 130 granola bars!"

He added: "I feel sorry for the person who lost their gold filling."

He said the store told him the bars are not made in the store.

We have contacted Tesco for comment.
