The gorillas at Prague Zoo were the focus of media attention around the
world a couple of years ago, when they were constantly monitored on the
internet, in a parody of reality TV shows like Big Brother. Today Prague
Zoo's gorillas remain very popular with the Czech public. However, it
seems not everyone likes them - on Tuesday apples studded with nails were
found in their enclosure, and officials say the apes could have suffered
serious injury.
