Squatters from the university occupied what they thought was an empty holiday home and changed the locks to prevent the owner's re-entry. It was in fact the permanent home of Edward Lumsden, an elderly man. When he returned home to find himself locked-out he called his daughter Vera Chadwick who came to the house to resolve the matter. She took a shotgun along with her. This gun was ultimately fired and one of the squatters - John Worsley - was shot and permanently blinded in one eye. (thetvdb.com)
