Police warned three juveniles Saturday night not to return to the McDonald's on Black Rock Turnpike after they allegedly threw food at patrons, got into an argument with a family, and made fun of a special-needs child, hitting her in the face with food.

The manager told police they also squirted ketchup onto the ceiling, slapped at light fixtures and insulted the restaurant staff. She asked that the youths be warned by police not to return.

One of the three was found in a parking lot across the street, and his father was called. Police conducted followups with the other two juveniles at their homes.

All three are Fairfield residents.
