A shop worker at The Mall in Cribbs Causeway has tested positive for coronavirus - but the shop has not yet been named.
The worker was diagnosed with COVID-19 on Friday (March 20) and is in self-isolation, according a memo from a company which manages the complex.
The retail store where the person was based is now closed and being cleaned 'thoroughly', the memo from CBRE said.
The shopping complex, which features John Lewis and Marks and Spencer, remains open.
Commonly-used areas such as entrances, security offices, toilets and food courts are being cleaned.

This afternoon, a spokesman was unable to provide a name of the store where the worker had been based.
The news comes a day after it was revealed there have been 23 people in Bristol have been diagnosed with coronavirus. In South Gloucestershire, there have been 17 confirmed cases.

He added: "In the meantime, please be assured the occupier is arranging for the working area to be cleaned and/or sanitised thoroughly."
