Quebec's workplace health and safety board has confirmed the initial hypothesis on how a 14-year-old lion at the Granby Zoo mauled a zookeeper earlier this month. The safety board found the door was left open due to human error. Additional security measuresNathalie Dufour, a spokeswoman for CNESST, said the zoo already had security measures in place leading up to the attack. "They're already applying this policy, and they've also boosted their security measures," she said. All three lions at the Granby Zoo were back in their usual enclosure on Wednesday.
