Three people were critically injured and a sheriff's deputy badly stung after a catering truck lost control and jumped a curb, hitting a tree and triggering a swarm of angry displaced bees.

City News Service reports that the catering truck was driving downhill on Saturday above the Sunset Strip in Los Angeles, when the driver lost control and hit the tree and street pole.

A sheriff's deputy tried to help three injured people trapped in the wrecked truck and surrounded by thousands of angry bees.

The deputy suffered an allergic reaction and was rushed to the hospital, where he was treated and released.

A fire spokeswoman says the three people were extricated in critical condition and taken to trauma centers. No one was cited.
