Hillsdale police said someone entered the Matsu Sushi Grill by breaking an exhaust fan in the back of the eatery early Saturday morning and made a meal, The Record of Bergen County (N.J.) reported Tuesday.
"He just wanted food, that's it," Detective Robert Francaviglia said. "He went in and pulled out a plate, got some chicken out of the freezer, got a rice box and fried up the chicken and rice in the frying pan. After he ate, he left."
Francaviglia said the burglar didn't touch $200 left in the cash register overnight.
He said police are looking into a possible connection with a similar incident late last year at a Kentucky Fried Chicken restaurant.
"It could be related," Francaviglia said. "It could be a homeless person looking for food."
