Staff at Southmead Hospital are being investigated after breaking coronavirus rules on a night out.
Prior to the second lockdown a group of staff were socialising without social distancing in place. Two of them have since received positive covid tests and the others are now self-isolating.
The hospital insists that no risk to patients has been identified.
An investigation is underway and the incident has been reported to 'relevant bodies'.
Hospital bosses have since reminded all staff of the need to strictly adhere to government guidance at all times. They say patients can continue to use their services confidently and attend planned appointments and procedures.
