The family of an elderly couple who died in an arson attack in Rugby have paid tribute to their memory and urged the public to help catch their killer.

Relatives of Kath and Albert Adams, who died after a mobility scooter was set on fire outside their home, described the 77-year-olds as the "rock" which united their family.

In a statement issued by Warwickshire Police, the pensioners' family, including their son Keith and daughter Nicola, said: "Kath and Albert were a lot of things to a lot of people - parents, grandparents, brother, sister, friends.

"They were really loved by their family and were the rock that pulled everyone together. Their tragic deaths have left a massive hole in our lives - that pain will never truly fade."

The statement continued: "Their door was always open and their children and grandchildren knew that all problems could be solved with a spoonful of rice pudding and copious amounts of tea.

"Despite their ill health in recent years, their cheeky sense of humour never left them - nor did Kath's love of shopping and Albert's love of football."

In their statement, the family said they had no knowledge of disruptive or anti-social behaviour in the area around the couple's home at a sheltered housing complex in Harold Cox Place, which they described as a "lovely supportive environment".

Appealing for anyone with information about the fatal blaze to contact Warwickshire Police, the family added: "Our lives will never be the same again. We are just comforted that they are at peace and are together.

"We ask for anybody that has any information to please come forward."

Detectives launched a homicide investigation on Monday after a second fire broke out near the Adams' home. Officers believe both fires were started deliberately and are connected.
