Rescuers say a street sweeper who was trying to clear something from the machine accidentally became entangled in it and was killed early Saturday.

It happened in the parking lot of a fast-food restaurant in Jacksonville.

Witnesses reported hearing the man crying for help.

By the time rescuers arrived, he had already died of his injuries.

Police say the victim was in his late 40s or early 50s. His name has not been released.

An investigator from the Occupational Safety and Health Administration was at the scene investigating.
