The family of one of four oil workers killed in a helicopter crash off Shetland have paid tribute a "fun, loving guy".
In a statement released by police, relatives of Gary McCrossan said: "A deep void has been left in our lives. Gary was a loving fiance - long-time partner to Fiona, devoted father to Niki and Freya, grandpa to Cohen, loving brother to Maureen, Frank and Kenny and best friend and confidant to many.
The statement continued: "He was a fun, loving guy who was full of life, a great story-teller - who always kept you guessing.
"Gary left a piece of himself in everyone he encountered and will be greatly missed. We walk each day in his honour."
