FAMILIES of Clutha victims have slammed delays to a report by air accident investigators.

The Air Accidents Investigation Branch last year said a draft final report would be circulated to "interested parties" in early 2015.

However the AAIB has refused to say when the final report will be released, only that it would be "in the middle of 2015".

Ian O'Prey, father of victim Mark O'Prey said: "They have put up a wall of silence."

Mark was one of 10 people who died after a police helicopter crashed through the roof of the Clutha pub on November 29, 2013.
