Police are looking for the man who has robbed four delivery men in a week. It seemed as though the same man had robbed three delivery men for Upper East Side restaurants, giving three different addresses on East 81st and East 82nd Streets, taking money, bikes and sometimes the delivery men's clothing. But on Saturday, he called for a order from Big Nick's, on the Upper West Side, met the delivery man in the lobby of a West 85th Street building, took the delivery man to the basement, then robbed him and took his bike. The police believe it's the same man and not a copy cat. We hope delivery men will just stay in the lobby or sidewalk where there are people.
