A man was flown from a construction site in Frederick early Thursday after a 2-ton backhoe bucket fell over a trench.
Police and fire officials were called at about 8:30 a.m. to Prospect Hall, the former site of St. John's Catholic Prep, on Butterfly Lane.
The man was working in a trench when the bucket fell from a backhoe, said Doug Brown, spokesman for the Division of Fire and Rescue Services.
The man was freed from the trench before rescue workers arrived and was flown from the scene because of the potential for serious internal injuries, Brown said.
Officials did not release the man's name Thursday.
