Police said they also had to hold dozens of 911 calls due to the lines getting clogged up, and apologized for the delays throughout the night.

Residents are being urged to only call 911 for emergencies and to use this online complaint form for reports of illegal fireworks.

“We ask that you please not call 911 for illegal fireworks unless someone is hurt or there is a fire. You are tying up 911 for other life-threatening emergencies,” a tweet from LAPD’s Communications Division said.
