UPDATE: Attorney says San Francisco Zoo security took 30 minutes to call 911

SAN FRANCISCO (AP) -- A lawyer for two survivors of a tiger attack at the San Francisco Zoo claims it took security guards 30 minutes to call 911.

Mark Geragos says the men, who are brothers, tried to get help for their friend when he was attacked by the animal on Christmas Day. The friend died of his injuries.

According to Geragos, the two men ran to a zoo cafe at about 4:30 p.m., but it was locked. He says they then told a security guard about the escaped tiger but the guard hesitated to act.

Police dispatch logs show that someone inside the cafe eventually called 911 at 5:07 p.m. It is unclear when the brothers tried to notify people in the cafe about the attack.

The zoo is dismissing Geragos' claim as unreliable. A spokesman says that San Francisco police still haven't finished their investigation.
