Man Unhurt After Sneaking Into Bear Exhibit At Zoo

SAN FRANCISCO, California (CNN) -- A man snuck into the grizzly bear exhibit at the San Francisco Zoo Saturday but was rescued immediately afterward without incident, authorities said.

A zoo visitor alerted the facility's staff about the 27-year-old man's presence inside the enclosure, said spokeswoman Gwendolyn Tornatore.

Staffers fired a warning shot to keep the two bears away from the man, before securing them inside their dens, Tornatore said in a statement.

The man, who was not identified, was conscious but unresponsive when he was rescued. He did not show any apparent signs of injury, Tornatore said.

It was not clear how the man got inside the enclosure, or what prompted him.
