CHARLOTTE, NC (WBTV) - One person was seriously injured and had to be rescued from the trails at the U.S. National Whitewater Center Sunday afternoon, MEDIC said.

The incident occurred around 12:11 p.m. in the 5000 block of Whitewater Center Parkway in Charlotte.

According to the West Mecklenburg Fire Department, a biker fell along the Carolina Thread Trail. MEDIC said the person was deep in the trails so the rescue was "challenging."

Firefighters said it took nearly a hour and a half to rescue the biker, and crews said it was roughly a two mile hike to get to the biker.

The person has life-threatening injuries, according to the West Mecklenburg Fire Department.

The person was airlifted to Carolinas Medical Center, MEDIC said.

No other information has been released at this time.
