Experts at Nottingham Trent University have been analysing a venomous spider that bit an elderly couple from Nottinghamshire.
Eddie and Bernice Kozlowski are now recovering from the bites. They caught the spider in their home in Gedling on Sunday.
Dr Chris Terrell-Nield, from Nottingham Trent University, has told ITV News Central the spider he has been analysing is part of the same family as the false widow - Britain's most venomous spider.
Earlier this month, a mother in Northampton escaped harm after she found a flesh-eating spiderin her bed.
