A giant, reverberating explosion rang out through the concrete of the Financial District on Monday at about 3:15 p.m., drawing fire trucks and police vehicles to the corner of Sutter and Montgomery Streets. The area was not closed down and crowds of office workers and curious lookie-loos stood by trading theories and taking photos.

The incident was, ultimately, a false alarm: Multiple first responders told Gazetteer SF that the cause of the explosion was a firework.

It’s unclear exactly where or how the firework ended up exploding near the intersection; firefighters and police officers on scene did not elaborate on any details. Bystanders speculated about the cause, and one man (who did not give his name) told Gazetteer that he had overheard first responders calling it a “prank.” 

First responders confirmed there were no injuries from the explosion. The fire trucks dispersed by about 3:35 p.m.
