"Lee took his son on a trip to London hoping to spend some quality time with him which was cut short by horrific and pointless attack," his family said in a statement.
"Lee would have had his birthday today but did not get to see his presents. He was an honest, bright person, who loved music very much, he knew history and art and he was a bachelor of science in Maths.
"He was devoted family man and did everything for his family. He was an honourable man and would always help somebody who was in trouble. He was a loving husband and father, he will be deeply missed by all his family."
