Armed Metropolitan police officers have fired "Hatton Rounds" - a type of shotgun blast - to stop a car on the A27 in Lewes. No-one was injured. There are long delays on the roads in the area. The police say no more details can be given at the moment.
It's thought to be the biggest bonfire night celebration in the world. 30 thousand people descended on the town of Lewes in Sussex last night to watch 6 bonfire societies parade through the narrow streets.
86 people were treated for minor injuries and 14 arrests were made. But overall, it was a spectacular night - Charlotte Wilkins was there.
Bonfire night preparations are underway across the South, but the biggest celebration will take place in Lewes in Sussex. 6 different societies compete at the event. Malcolm Shaw went to last year's parade.
