The remains of a 30-year-old man were pulled out of the Hudson River in Manhattan on Monday, police said.

The NYPD Harbor Unit recovered the body from the water around 45th Street and 12th Avenue just after 12 p.m., according to cops.

The Harbor Unit went to the scene after a 911 caller reported seeing the body, cops said.

“It seems like he’d been in the water for a while,” a police source said.

The man had identification on him but his identity was pending family notification, police said.

The city’s Medical Examiner’s Office will determine the cause of death.
