Customers had complained of a stench when visiting the Tesco Extra store in The Forum area of Stevenage town centre.

A spokeswoman for the supermarket told the Comet: "We're sorry about the smell at our Stevenage Extra store.

"It was caused by a blocked drain which has now been fixed."

There was a similar issue at the superstore in January 2018 - a mystery which puzzled shoppers over the course of a weekend.
