Penny Upton, a friend of the homeowner Esme Barrett, went to Mr Tull's aid before paramedics arrived. She said today: "He was using an axe, then said, 'Ouch' and suddenly there were an awful lot of wasps. His throat swelled and he could not breathe but I have a couple of friends with adrenaline pens so I knew about these things and could tell the paramedics what was wrong. They were here within five minutes.
