Mr Baker said: 'There is no question of attributing blame to them. It was just a freak accident that could have happened at two in the afternoon. They were a wonderful couple. They clearly cared for each other a great deal. They had just come back from a tour of Europe. They were very happy and in love, by all accountts. Stuart was like a brother to me. We had known each other since childhood. 'It's left a massive void in my life. I'm still numb, in complete disbelief. He is going to be sorely missed. He was one of those people who was so full of life. A friend of Mr Mead, who wanted to remain anonymous, said: 'We are just completely devastated. At least we know they weren't chased or mugged in the street but two people who may have died through negligence. We were told there is CCTV footage of the incident taken from the building opposite.
