Southampton University lab experiment sparks chemical alert
An overnight experiment at a University of Southampton laboratory has triggered a major emergency response.
Fire crews, specialist appliances and a hazardous materials team were called to the laboratory in University Road just after 06:00 BST.
Hampshire Fire and Rescue said fumes in the laboratory from the experiment which "had not performed as it should" had triggered the fire alarm.
Fire crews have now left the scene and road closures have been lifted.
