California town swarmed by angry bees safe again, says expert

• Two dogs were killed and several people stung in Concord
• 'They were all over my hair - I had to shake it out,' says resident

A bee expert says a northern California neighborhood overtaken by a swarm of aggressive bees, which are suspected of killing two dogs and stinging several people, is considerably safer after the insects made it back to their cluster.

"These bees are a little off the wall. We've been having Africanized bees moving into California for quite a few years up from South America," Norm Lott, of the Mount Diablo Beekeepers Association, told local KGO News.
