LINCOLN, R.I. (WPRI) — An investigation is underway after a teenage boy was pulled from the water at Lincoln Woods State Park on Sunday.

The incident occurred shortly after the beach was closed and lifeguards were off duty at 6 p.m., according to the R.I. Department of Environmental Management (DEM).

A fisherman in the area said he witnessed a group of kids holding hands in the water looking for someone.

An off-duty lifeguard heard the commotion, according to a DEM spokesperson, and swam out to find the 15-year-old victim.

The lifeguard performed CPR before the boy was taken to Hasbro Children’s Hospital. He is currently in critical condition as of Monday morning.
