The following is a live account of events currently unfolding by Trident contributor Tom Boon. More details will follow when we have them.
At 13:40 on Friday 8th December a fire alarm started to sound in the Wright building. After the building was evacuated, two fire engines from St Albans arrived escorted by UH Security. It quickly became apparent that this was a real emergency when the fire crews started to run inside with breathing apparatus and hoses.
14:15 UPDATE: Police have arrived on site, accompanied by another Fire Engine.
14:40 UPDATE: The fire appears to be out, the final Fire Engine has now left, an hour after the alarm originally sounded. The Wright building is set to reopen at 15:30
This is a developing story, more follows.
