Actor Ray Buffer is being accused by a San Diego comic book store of stealing some pricey comics ... and the store says security footage appears to show him stuffing 'em up his shirt.
Southern California Comics in San Diego alleges it has Ray on video stealing $600 worth of comic books, and the store filed a police report with SDPD and is handing over evidence to police, including their security footage.
SDPD tells TMZ police took a report for petty theft and are investigating the incident.
The comic book store says it got even more evidence -- which it will be turning over to police -- after warning other stores about Ray in a Facebook post before he had been identified.
The owners tell us Metropolis Comics in L.A. sent them some eerily similar security footage from when Ray was there. In that video, the owner confronts him after seeing him pull the same move, and this time he puts the comics back and leaves as the owner threatens to call police.
Ray, who has appeared in TV shows like "ER" and "Curb Your Enthusiasm," deleted all of his social media accounts after the comic book store posted the video online.
Bookstores are always on edge about this kind of theft, because some comics are worth a lot of money -- we've reported about rare comics getting auctioned off for large sums. That's why most stores have such great security cameras.
We reached out to Ray ... so far, no word back.
