A swarm of aggressive bees have been attacking a town in Northern California.

CONCORD, Calif. -- 

CBS News spoke online with professional beekeeper Norman Lott, who's helping rid the neighborhood of the bees.

He said he has never seen anything like it.

"This is a new situation that we're gonna have to deal with," he said.

Police have barred pedestrians from part of the neighborhood where most of the attacks have happened, while beekeepers work to safely remove the bees.

They're hopeful most, if not all of the bees, will be out of the neighborhood by Sunday night.
