TD Garden officials are investigating after a fire alarm went off Wednesday night, triggering an evacuation of the arena about an hour after the Boston Celtics playoff game against the New York Knicks, officials said. “The cause of the fire alarm is currently under investigation,” according to a TD Garden statement Thursday.

Reporters and players reportedly evacuated TD Garden. No one was injured, and the cause of the fire alarm is currently under investigation.

As if fans needed another reason to head for the exit after a Celtics playoff loss, authorities say the fire alarm also went off.
