Police in New York say at least five people, including three infants, were stabbed at an overnight day care centre in Queens.
NBC New York reports that authorities say the stabbings happened just before 04:00 on Friday. One of the infants, a girl, is in serious condition, but none of the injuries is considered life-threatening.
A sixth person was found in the basement of the day care centre in the Flushing neighbourhood. Police say she had slashed her left wrist and is in custody at a hospital.
Police say a man who was injured was stabbed in the leg and is the father of a child who was at the day care centre. It isn't clear whether his child was among those stabbed. Another adult who was hurt is a woman who works at the centre.
A motive for the stabbings hasn't been determined.
