The US Coast Guard and local crews are searching for a possible person in the water off the coast of Greenwich.
USCG officials said a Good Samaritan found a paddleboard between Calf Island and Shell Island around 5:50 p.m. Thursday.
Crews responded and found an oar approximately a quarter mile southwest of Calf Island. Rescuers are searching the area.
Anyone with information on the owner of the paddleboard should contact the USCG at 203-468-4444.
