A 41-year-old man was injured Friday after falling off his mountain bike in White Clay Creek State Park.
The accident happened at 12:17 p.m. in the 100 block of Smith Mill Road in the eastern part of the park near Paper Mill Road, said Cpl. Abigail Haas, a spokeswoman for New Castle County Paramedics.
Friends of the biker alerted New Castle County Police K-9 units that were training nearby, according to a statement from Aetna Hose, Hook and Ladder Co.
Firefighters and paramedics rushed to the scene and treated the man for possible injuries to his arm, chest and back.
A Delaware State Police helicopter flew him to Christiana Hospital, where he was listed in serious condition.
