A Liverpool city centre Subway restaurant "voluntarily closed" its doors following an environmental health inspection.
The branch in Exchange Street East, which is run under a franchise, has since fully re-opened. Neither Liverpool Council nor Subway were able to confirm the reason for the temporary closure.
People who said they were former workers at the Subway branch have shared pictures with the ECHO which they claimed were taken there last November and which appear to show there was then a problem with mice. They also showed the ECHO WhatsApp messages they said were exchanges between staff about the "mice problem".
