Officers ultimately took a man away in stretcher. It was not immediately known if he was injured.

Suffolk County police could not immediately be reached for comment.

The incident came at a time when the trains were not running. Buses replaced trains between Ronkonkoma and Brentwood all day on Saturday because of track work.
