Tributes paid to 11-year-old Aberdeen A90 victim Bobby Douglas Described as "the original rascal who had a heart of gold" by those who knew him, the schoolboy had been taken by ambulance to Royal Aberdeen Children's Hospital, but later died from his injuries. This morning, members of Bobby's club and gym - Aberdeen Combat Centre - paid tribute to the boy they called "a wee diamond." In a statement released on their Facebook page, they said: "It is with a truly heavy heart that I have to make this announcement. Last night, we lost one of our boys. One of our Spartans. I'm honestly dumbfounded trying to find words that will emphasise just how truly saddened and shocked we are. Bobby was only 11 years old, the original Mini Spartan. He has been such an important part of the ACC and the Spartans since we began many years ago, and his sudden passing has left us all unbelievably devastated and shocked. Such an amazing kid, who literally touched the lives of every single person who met him, and no words can describe the sadness we feel today. Our flag flies at half mast today. Words can't express the sadness. All our love bobster xx Members of the local community left flowers and messages outside the gym on South College Street, in tribute to Bobby.
