As far as suspects go, this one is pretty sketchy.

Police in California are trying to track down a crook using a caricature drawing he left behind after allegedly robbing the artist of $500.

“Do you recognize this caricature? And no, we are not kidding…,” Riverside Police posted on Facebook Tuesday.

Police say the suspect had his portrait drawn on Dec. 5 during the Festival of Lights in downtown Riverside.

Once the artist was finished, he “grabbed a money bag” and ran, leaving behind the clue, police said.

“This caricature is of the suspect, but of course, has exaggerated characteristics and features,” cops said.
