Six people were brought to the hospital after a man wielding a butcher knife threatened to stab a bus driver and tried to slash tires at a Boston transit station on Friday before being taken into custody, authorities said.

Among those injured were two transit officers, a Boston police officer and the suspect in the case, said Richard Sullivan, superintendent of police for the Massachusetts Bay transportation authority. Sullivan, who briefed reporters at a news conference, said he wasn't aware of the other two reported as injured by Boston's emergency medical services agency.
