The city's medical examiner is looking into what caused a 3-year-old Brooklyn boy to die while he was at day care Saturday.
Cops responded to a 911 call at a house near 65th Street and 21st Avenue in Bensonhurst around 3:30 p.m., where they found Andy Li unconscious.
The boy's parents, who reside in Sheepshead Bay, dropped him off at the home earlier in the day, police said.
Li was taken to Maimonides Medical Center, where he was pronounced dead.
No criminality was suspected in the boy's death as of Sunday, and the investigation is ongoing, according to the NYPD.
