Check out this video that was supposedly taken in an alleyway in Indonesia, where it shows a circus-like, small simian rolling up to a group of kids on a mini motorbike ... which it jumps off of right in front of them, and then attempts to take the runt of the litter.

It's a wild scene -- something out of a damn movie, but this rogue little bastard does his own stunts! -- and it only gets scarier the more you watch. The monkey, at first, loses its grip on the child (who's screaming) but then goes back and starts dragging them by the hand.

The monkey decides yanking the kid by the hair would make for a better escape and tries that -- and it even gets pretty damn far with the child too ... before some reasonable adults FINALLY step in and scare it off. You can hear it shrieking in the distance as it runs off.

Now, for a little context ... the guy who shot this video spoke to a local media outlet, and said owning monkeys is actually illegal out there -- but people still do keep 'em as pets and use them for entertainment 'cause the consequences are so minimal.

If anything, hopefully, this serves as a wake-up call to Indonesian officials -- these hominids don't just play nice and play accordions ... they're literally capable of taking your children.

Monkey see ... monkey abduct!!!
