LEWISTON — A 16-month-old boy was taken Sunday afternoon to Central Maine Medical Center after being found outside an apartment building on Knox Street.

Lewiston police said the boy left an apartment at 10 Knox St., and was outside for 10 to 15 minutes before being found by a passer-by.

Police Lt. David St. Pierre said the child was taken to the hospital at about 3:45 p.m. as a precaution, due to exposure to the cold. The boy did not appear to be injured, St. Pierre said.

St. Pierre said an investigation was underway to determine if charges will be filed. The matter has also been referred to the Maine Department of Health and Human Services.
