Overview

• Ryan Satterthwaite, 19, died Monday night in hospital after suffering a serious head injury during an informal 'run-it-straight-style' game with friends.
• Inspector Ross Grantham said the incident is being investigated on behalf of the coroner and is not being treated as a criminal matter.
• The social media-driven tackle game involves participants colliding at full speed without protective gear and has spread through both impromptu matches and semi-official competitions.
• Last week at Auckland’s Trust Arena two men were knocked unconscious and one appeared to have a seizure during a cash-prize 'Run It Straight' event.
• Neuroscientists and New Zealand Rugby have warned the trend poses serious brain injury risks while critics say large cash prizes exploit financially vulnerable participants.
