An 11-year-old boy who died after falling from a zip wire at a Gwynedd adventure park had been wrongly attached to the ride, an inquest has heard.
Bailey Sumner from Blackpool died when he fell from the 475-ft long SwampFlyer ride at the Greenwood Forest Park in April 2011.
The ride had opened just a week before, after passing a safety inspection.
The inquest at Dolgellau heard a carabiner clip was connected to a "false loop" in the safety attachment.
The hearing, which is due to last three days, continues.
