Police and a bomb disposal unit have been called to an incident near coronavirus vaccine factory.
The emergency response is in place on Wrexham Industrial Estate and is currently closed off near the Wockhardt factory.
The plant is being used to help produce the Oxford/AstraZeneca vaccine, North Wales Live reports.
A spokesman for North Wales Police said: "We are currently dealing with an ongoing incident on the Wrexham Industrial Estate.
"The roads are currently closed and we would ask the public to avoid the area until further notice."
The Wockhardt factory is considered a sensitive site given its importance to the UK’s Covid-19 vaccination programme.
As a ‘fill and finish’ site, it bottles vials of vaccine ready for distribution across the country.
Last November the factory was visited by Prime Minister Boris Johnson who said the lab could provide “salvation for humanity” .
