Crews said they were searching Lake Mohegan for a possible missing swimmer on Friday afternoon.
Fairfield Police Chief Gary MacNamara said officials received a report of a swimmer in the water and no one saw that person return to shore.
Crews are searching the lake and have cleared the beach. No clothes or bikes were left behind.
A woman and her two children said they saw a boy go under the water and never come back out.
On Friday evening at about 7 p.m. officials canceled the search as they said nobody was found and there were no reports of a missing person.
