Los Angeles - Vin Diesel has paid tribute to the late Paul Walker, calling him a "special angel".
Alongside his co-stars of Fast and Furious 7, the 47-year-old actor thanked the film's fans for their touching words about his "brother", who died aged just 40 in a car crash in Los Angeles last year.
Speaking at the premiere of the film's trailer, Paul's co-star, Tyrese Gibson said: "Even when that moment happened, of us losing our family and Paul, we all have significant others ... or not, we all have our own immediate circle of family and friends and loved ones, but they didn't know Paul the way we knew Paul.
