Terrified patients forced to flee major hospital 'in the dark' after power outage

Patients have spoken of the dramatic moment they were forced to evacuate a major city hospital 'in the dark' after a critical incident was declared. People being treated at the Bristol Royal Infirmary said they heard what some thought was an 'explosion' as they were plunged into darkness and told to leave the site immediately. Multiple emergency services remain at the scene in Bristol city centre after what hospital bosses have since described as a 'power outage'. But those forced to flee said there was significant confusion about what was happening - with some claiming it was a ceiling collapse and others saying sparks were flying causing a fire. Lisa Davidson, 50, a housewife from Bristol, was having a blood infusion inside for Crohn's disease. She said: "All the lights went off and they kept flashing on and off. Then they told us to go out, we couldn’t find our way out.
