Searching a meaning of a Japanese word okibiki.
I have found a definition:
walking away with another's bag
But you can call someone a okibiki. Analyzing it, the person is a bag thief. Then in English, there is another single word to define it?
If not, is usual to say "bag thief"?

The only more-or-less common English expressions that come close to it in meaning I can think of are all two words (though they could be hyphenated):
bag-snatcher, purse-snatcher, and perhaps (if they're only taking a wallet) wallet-lifter -- and that one's quite a bit rarer in usage (and pickpocket would probably be more common for that case).
There's the archaic cutpurse, but that doesn't quite fit.
While "bag-thief" is clear enough, bag-snatcher is probably more idiomatic.
