A zookeeper, identified only as "Martin. H," was killed by a Siberian tiger in front of zoo visitors on Thursday.
Apparently, the 56-year-old man forgot to lock a cage door and while he was laying out food in the outside area of a tiger exhibit in a zoo in Munster, Germany.
The tiger (pictured) was supposed to be locked up in a cage, but instead crept up behind the zookeeper and bit him in the throat.
"The [zookeeper] had no chance, he was killed instantly," said fire department spokesman Dieter Knaack.
There is an investigation into the tragedy, but it is believed the cause of his death was human error.
"An encounter like that with a tiger isn't something that can be survived. We can install only so much technology and so many alarms, when it comes down to it, it's the keeper who decides,'" Zoo chief Jorg Adler told the The Local.
The 10-year-old Siberian tiger, "Rasputin," will not be killed. He was transferred to this zoo from another facility in 2005, notes 9News MSN.
