A day care worker remains in custody after allegedly stabbing two adults and three infants—who were all younger than a month old—at a New York City maternity center early Friday.

The New York Daily News reported that it’s still unclear why Yu Fen Wang, 52, wielded a meat cleaver and knife and embarked on a rampage that left five people injured at Mei Xin Care Inc. in Queens at around 3:45 a.m. Authorities said all five victims will likely survive their injuries.

WNBC reported that a 13-day-old girl and a 1-month-old girl sustained stomach wounds while a 22-day-old girl suffered cuts to her ear, chin, and lip. Sources told the Daily News that a 31-year-old man was stabbed in the wrist, leg, and knee while a 63-year-old was stabbed in the leg and arm.

Two 911 calls obtained by the news station painted a chaotic scene. One of the callers begged for the dispatcher to hurry up because their baby had been stabbed twice.

“I’m sleeping… and then I heard somebody yelling … and then they are killing people,” one of the callers said. “I just saw the blood on the floor … and that somebody got hurt.”

Locals revealed to the Daily News that the “day care” actually provided temporary housing to pregnant Chinese immigrants who would have their babies and seek citizenship.

A spokeswoman for the state’s Office of Children and Family Services confirmed to WNBC that the Queens facility wasn’t an OCFS-licensed or regulated childcare program.

Wang is in police custody as she remains hospitalized for critical injuries she suffered when she allegedly slit her own writsts. Charges are currently pending.
