An investigation is underway after a man's body was pulled from Norwalk Harbor Tuesday morning.

Police said a 911 call came in around 9:40 a.m. from a boater in the inner harbor who reported a body floating in the water. Marine units from the police department and fire department responded to the boater’s spot, pulled the body out, and returned to shore where they were joined by the detective bureau, according to police.

“Preliminarily, it doesn't appear there are any injuries so that's where the ME's office will come in in giving us a cause of death,” said Lt. Joseph Dinho.

The medical examiner's office will also determine the timeline of when the man went into the water.

“Just based on previous experience, it doesn't appear to be a very long period of time but certainly more than a couple hours,” Dinho told News 12.

Dinho said the man didn't have identification on him, and added there are no reports of a missing man in Norwalk.

Some people living along River Drive and Wallace Avenue came out of their homes to watch the atypical action in the neighborhood.

“There's a huge appeal to this neighborhood, obviously. It's a small, coastal, beachfront community,” Brett Minieri said. “It’s very quiet, and we like it that way.”

Tuesday morning was the exception, with the area abuzz.

“I heard all the ruckus, and I saw on social media that a body was discovered which is always sad news,” he said.

Minieri told News 12 he sees swimmers and boaters out there round the clock.

“It's not strange to see people out at all hours of the evening even into the night. You assume they know what they're doing, but accidents happen,” he said.

It's not known if that's what occurred in this instance. Police ask anyone with information to reach out to Detective Taylor at 203- 854-3183 or ltaylor@norwalkct.gov. Anonymous tips can be left through the Norwalk Police Tip Line at 203-854-111.
