Zoo evacuated after mass chimp break-out - ABC News (Australian Broadcasting Corporation):

A zoo in north-west England was evacuated on Sunday after about 30 chimpanzees escaped from their enclosure.

The animals escaped from 'Chimp Island' and found their way into a keeper area where their food is prepared, the zoo said.

More than 5,000 visitors were asked to leave Chester Zoo, near Liverpool, shortly after the break-out as keepers rounded up the chimps.

Come on, it's near Liverpool. After hordes of soccer hooligans, how scary can 30 hungry chimps really be?
