Wanted: the shirtless reptile-hurlers of Humpty Doo.

It sounds like a crazy caper in a children’s book. But the police in Australia are serious.

Investigators in the Northern Territory announced on Sunday that they needed the public’s help in identifying four half-naked men who had broken into a school office in the town of Humpty Doo, shattering a window and heaving a few saltwater crocodiles inside.

Presumably, investigators also want the answer to that age-old question of crime-solving: Why did you do it?

The police released a security camera video of the break-in, which occurred around 5 a.m. on Sunday. The video shows the interior of an unremarkable office: desk, file cabinets, computer. Then the panes of a glass door tremble and crack, and in comes a crocodile, toppling headfirst into the room. The scaly beast is followed by another, and then a third crocodile flops headfirst through the broken glass.
