Relatives of 51-year-old Nigel Key, who was pronounced dead after police were called to Matley Gardens, Totton, Southampton, on Thursday, have described him as a “devoted family man”.

A Hampshire Constabulary spokesman said that the 31-year-old suspect, who is from Totton, was arrested on suspicion of murder before being taken to hospital for medical treatment.
