It took a few weeks, but cops have finally arrested a man they believe snatched a TMZ camera from a TMZ photog (while it was recording) …. and it’s all because the perp did the most stereotypical bad guy thing ever — he returned to the scene of the crime!

It all went down at L.A. County Superior Court yesterday, when our cameraman was trying to shoot Kid Rock — and noticed the suspect walking around the very area where our photog was jacked last month.

Our photog tipped off the cops, who swarmed in and made an arrest — and of course, our photog recorded the whole thing … while holding on to his camera this time.

FYI — the perp’s name is Ysuef Bichem … and if he’s convicted, dude could become someone else’s Bichem behind bars.
