RIVERSIDE, Calif. (KABC) -- It's not your average suspect sketch, but Riverside police are hoping a drawing will help them find a man who is suspected of robbing a caricature artist.Police say the suspect approached the victim at the Festival of Lights event in downtown Riverside on Dec. 5 and asked him for a portrait of himself.After the artist finished the caricature, the suspect grabbed a money bag from the victim, which contained about $500. The suspect then ran away, leaving the portrait behind.Police say the caricature is of the suspect, but has exaggerated characteristics and features. The suspect is described as a black man in his early 20s, about 5 feet 1 inch tall, with black hair and mustache. He was last seen wearing a blue and red jacket, black pants and a red hat.Anyone with information about the suspect is urged to contact Riverside detectives at (951) 826-2054.
