The teenager who fell down a ravine at a popular Perth park yesterday is now fighting for life after his condition deteriorated.
The 15-year-old had been out in the wet weather at Bells Rapids Park when he slipped and fell around 2pm on Friday.
According to 7NEWS, the teen was hiking with his parents at the popular Brigadoon spot when he slipped and slid down a ravine.
The fall sparked a massive rescue operation that involved a dozen fire crews and paramedics.
The teen was eventually pulled free after more than two hours.
He was raced to Royal Perth Hospital in a serious condition.
But his condition has worsened overnight and he remains in the intensive care unit with very serious head injuries and a broken arm.
A second person was also injured in the rescue on Friday.
That person sustained non life-threatening injuries.
