Rumor has it that the escalator suddenly stopped and could not walk.

Does the subject want to ask, "Is it a rumor that the escalator suddenly stopped and can't leave?" No. The sudden stop of the escalator is not a rumor, but a safety reminder. When the escalator suddenly stops running, it will lead to crowded people and even safety accidents such as trampling. Therefore, when the escalator suddenly stops, don't try to move on, but stay where you are and wait for the escalator to restart or find other safety exits.
