STRATFORD, Conn. (AP) Workplace safety officials are investigating an accident involving a saw that killed a construction worker at a southwestern Connecticut airport.

The Connecticut Post reports that the worker was pronounced dead at the scene Thursday at Sikorsky Memorial Airport in Stratford after a gasoline-powered saw he was using kicked back and caused a fatal injury to his neck.

The worker has been identified as 57-year old Antonio Simoes of Naugatuck. A spokesman for Bridgeport Mayor Bill Finch says the man was an employee of Manafort Brothers Construction in Plainville.

The accident happened during a $17 million construction project at the airport that includes runway improvements. The airport was closed after the accident, but resumed operations about two hours later.

Bridgeport and Stratford police and inspectors from the U.S. Occupational Safety and Health Administration are investigating.
