from a peaceful march to...bang

Does "bang" here mean "banging/heavily knocking at the door"?

********************
“It went from a peaceful march, calling out the names, to all of a sudden, bang, ‘How dare you fly the American flag?’” said Mr. Moses, who is Black and runs a nonprofit group in the Portland, Ore., area. “They said take it down. They wouldn’t leave. They said they’re going to come back and burn the house down.”

Mr. Moses and others blocked the demonstrators and told them to leave.
