CHICAGO – A Chicago man on probation for a weapons conviction sent threatening photos of himself armed with a shotgun to a chef at a popular Oak Park restaurant where he had recently been fired, authorities said Monday.

Chicago police released a photo that allegedly shows the suspect, identified as Nicholas Claxton, holding up a cellphone and taking his own picture in a mirror. The man in the photo is clad in a camouflaged, bulletproof vest and black ski mask that covers most of his face. He has night-vision goggles perched on his head and is clutching a shotgun in his left hand.

Prosecutors said Claxton, 23, texted the photo to a chef at the Maya del Sol restaurant on July 28, five days after he was fired as a line cook. Claxton was also “upset that his former employer had accessed his credit report three times,” Assistant State’s Attorney Lorraine Scaduto said.
