Tony Walter worked at a law firm near Edgware Road Underground station, where there was a suicide attack on July 7, 2005 that caused 6 victims.
Since then Walter has been affected and had been particularly distressed by the recent attacks in Westminster and Manchester.
He took time off work in March, after Birmingham-based terrorist Khalid Masood drove into several people on Westminster Bridge and stabbed police officer Keith Palmer.
People close to Walter -52-year-old’s- said that he considered himself “the 23rd victim of the Manchester Arena attack”. He was found at his home in Tottenham, North London, on Wednesday – around 40 hours after the Manchester attacks and he is being treated as a suicide.
During his bereavement farewell Walter’s sister-in-law, Sheila Walter, led the tributes.
“It’s a tragedy and we’re devastated. Tony was such a lovely man,” she said.
The Manchester Arena bombing saw 22 people lose their lives, including 10 children and teens.
