SAN FRANCISCO (KGO) -- Illegal fireworks are once again lighting up the Bay Area skies on this Fourth of July.
SKY7 was over the region capturing illegal fireworks, as well as some sideshows happening all around.
So far, we've seen illegal fireworks in cities including San Francisco, Oakland and Union City.
ABC7 News spoke with Steve Hill from the Contra Costa Fire Department to see how they've prepared for these type of events.
Hill warns residents of the potential dangers that come from these illegal shows.
"They're dangerous in terms of the injuries they create. Every year unfortunately we've already had some injuries in Contra Costa this year as a result of fireworks," Hill said.
Contra Costa Fire will have a command post set up in Pleasant Hill for the rest of Tuesday night.
